eCryptfs: Print FNEK sig properly in /proc/mounts
The filename encryption key signature is not properly displayed in
/proc/mounts. The "ecryptfs_sig=" mount option name is displayed for
all global authentication tokens, included those for filename keys.
This patch checks the global authentication token flags to determine if
the key is a FEKEK or FNEK and prints the appropriate mount option name
before the signature.
