This commit uses the GitHub Actions cache to ensure that the `rtf`
binary can be re-used between runs if it hasn't changed.
It also caches the linuxkit binaries for use in future stages.

This commit adds the GCP test that formerly ran in LinuxKitCI to run
under rtf.
As GitHub Actions doesn't currently support adding secret files, I've
skipped this test for now. Credentials can be passed via environment
variable but as RTF runs with `-x` the contents is viewable in the logs.
I will create an issue to follow up and find either a way of writing the
variable to file that doesn't compromise it. Or perhaps another approach
that is more compatible with GH actions

This commit adds a GitHub Actions workflow to replace both CircleCI and
LinuxKit CI.
It will build the Linuxkit binary, run tests and upload artifacts
It replaces the Integration Tests that are run by Linuxkit CI via
the make ci or make ci-pr targets with multiple sets of Integration
Tests that are run in parallel.
It does not yet test GCP. The GCP test in LinuxKit CI could be moved to RTF

This new snapshot comes from the brand new linux-compat repo, which
follows the recent upstreaming into net-next. When Linux 5.6 lands in
LinuxKit, we'll be able to remove the module entirely.

This adds a new configuration provider that just reads a file.
This is needed for Docker Desktop, where we will run a LinuxKit distro in an isolated namespace within WSL 2.
In this scenario, the config will be accessible trough the WSL2 built-in 9p mount of the Windows filesystem.

Allows us to drop some patches we were carrying, since the bugs were
fixed upstream. Gives numerous tooling improvements too.

Re-enable perf builds for 5.3.x and 4.19.x since they're the latest
stable and LTS, respectively.
Update the bcc build rules to map to these same kernel releases, too.

The first patch re-adds symbol definitions that were temporarily omitted
from the 4.19 stable branch.
The latter patch corrects the uapi swab.h to that errors about "unknown
type name '__always_inline'" are no longer present in builds. Without
this patch, bcc would build but attempts to compile the internal
programs at runtime would fail.

There were some mistakes made in the initial code where writes didn't work, this commit fixes that.

If the swap disk is larger than 1MiB, then use a 1MiB blocksize in `dd`
On my machine using a large block size speeds up swap file creation:
```
/ # time dd if=/dev/zero of=output bs=1024 count=1048576
1048576+0 records in
1048576+0 records out
real 0m 4.61s
user 0m 0.79s
sys 0m 3.77s
/ # time dd if=/dev/zero of=output bs=1048576 count=1024
1024+0 records in
1024+0 records out
real 0m 1.06s
