Michael Hudson-Doyle 1f4e90d468 linux: return UNSUPPORTED from tst-mount if entering mount namespace fails
Before this the test fails if run in a chroot by a non-root user:

Checking that the test can enter a new mount namespace is more correct
than just checking the return value of support_become_root() as the test
code changes the mount namespace it runs in so running it as root on a
system that does not support mount namespaces should still skip.

Also change the test to remove the unnecessary fork.
