ext4: do not advertise encryption support when disabled
The sysfs file /sys/fs/ext4/features/encryption was present on kernels
compiled with CONFIG_EXT4_FS_ENCRYPTION=n. This was misleading because
such kernels do not actually support ext4 encryption. Therefore, only
provide this file on kernels compiled with CONFIG_EXT4_FS_ENCRYPTION=y.
Note: since the ext4 feature files are all hardcoded to have a contents
of "supported", it really is the presence or absence of the file that is
significant, not the contents (and this change reflects that).
