[PATCH v2 3/3] cifs: skip tests that need POSIX support for nounix mounts

[Pavel Shilovsky <pshilovsky@samba.org>]

CIFS/SMB protocol without POSIX extensions doesn't support operations
with symbolic links and advisory byte-range locks from the same process.
Add a check for nounix mounts and use it in generic tests that
require such operations.
