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.
