Pavel Tikhomirov 5c11b0e440 zdtm: check that unbindable mount flag does not affect restore

Make two mounts, binds of the same file system, the first has root "/"
and the second has a cut root "/auxiliary". This insures that on restore
criu will mount the first mount first and latter bind the second from
it. After set the first mount unbindable to check if restoring these
flag does not interfere with restoring mounts.

Before the fix in these series we had the error:

(00.031286)      1: mnt: 	Mounting tmpfs @/tmp/.criu.mntns.wGroPU/12-0000000000/zdtm/static/unbindable.test/bind_of_unbindable (0)
