Fix tests that fail with true read only

Mounting a directory inside a read only container requires that to be created in advance, but `runc` worked around that if the rootfs was not originally read only. You cannot even bind mount a file that does not exist into a read only container. The containerd test is given a disk, as running on an overlay does not work; however it is also disabled as one of the parts of the test is failing, needs investigation.
