Ecryptfs: Add mount option to check uid of device being mounted = expect uid
commit 764355487ea220fdc2faf128d577d7f679b91f97 upstream.
Close a TOCTOU race for mounts done via ecryptfs-mount-private. The mount
source (device) can be raced when the ownership test is done in userspace.
Provide Ecryptfs a means to force the uid check at mount time.
