ecryptfs: added ecryptfs_mount_auth_tok_only mount parameter
This patch adds a new mount parameter 'ecryptfs_mount_auth_tok_only' to force ecryptfs to use only authentication tokens which signature has been specified at mount time with parameters 'ecryptfs_sig' and 'ecryptfs_fnek_sig'. In this way, after disabling the passthrough and the encrypted view modes, it's possible to make available to users only files encrypted with the specified authentication token.
