rootfs.sh fails on machines with SELinux in enforcing mode if the
volumes aren't labelled.
This patch labels volumes so the container is able to access them.
In order to do this rootfs directory creation must be moved before the
Docker container is started. Previously docker-run(1) would create the
rootfs directory in the USE_DOCKER case.

The "ephemeral" is just used to indicate ephemeral volumes in
runtime. We should not pass it to agent. Instead, "bind" should be
the correct mount type to be passed.

Re-implement image builder script to generate an image with a double MBR +
a DAX metadata. The DAX metadata is read by the NVDIMM driver to know the
beginning of the data in the pmem device.
This new image format is required to enable DAX in the kernels and hypervisors
that support NVDIMM, without breaking the compatibility with the kernels and
hypervisors that don't support it.
Following diagram shows how the resulting image will look like
```
.-----------.----------.---------------.-----------.
| 0 - 512 B | 4 - 8 Kb | 2M - 2M+512B | 3M |
|-----------+----------+---------------+-----------+
| MBR #1 | DAX | MBR #2 | Rootfs |
'-----------'----------'---------------'-----------+
| | ^ | ^
| '-data-' '--------'
| |
'--------rootfs-partition---------'
```
MBR: Master boot record.
DAX: Metadata required by the NVDIMM driver to enable DAX in the guest [1][2]
(struct nd_pfn_sb).
Rootfs: partition that contains the root filesystem (/usr, /bin, etc).
Kernels and hypervisors that support DAX/NVDIMM read the MBR #2,
otherwise MBR #1 is read.

Detect failing test case:
```
....
=== RUN TestEnterContainerFailingContNotStarted
--- PASS: TestEnterContainerFailingContNotStarted (0.01s)
=== RUN TestEnterContainer
--- FAIL: TestEnterContainer (0.00s)
Error Trace: sandbox_test.go:1154
Error: Expected value not to be nil.

Error Trace: sandbox_test.go:1157
Error: Expected nil, but got: &errors.errorString{s:"Can not

Messages: Failed to start sandbox: Can not move from running to

```
`TestEnterContainerFailingContNotStarted` calls `cleanUp` at function
begging but it doesn't clean its garbage after it ends.
`TestEnterContainer` only call `cleanUp` in the end but it doesn't do
cleanUp in the begging, that gives first test case a chance to impact
latter one.
This commit modifies all the test cases, let them all do the cleanUp()
in the end.
The policy here is: "everyone needs to take their garbage away when they
leave" :)

k8s host empty-dir is equivalent to docker volumes.
For this case, we should just use the host directory even
for system directories.
Move the isEphemeral function to virtcontainers to not
introduce cyclic dependency.

We handle system directories differently, if its a bind mount
we mount the guest system directory to the container mount and
skip the 9p share mount.
However, we should not do this for docker volumes which are directories
created by Docker.
This introduces a Docker specific check, but that is the only
information available to us at the OCI layer.
