ext4: move procfs registration code to fs/ext4/sysfs.c

Browse Source 
This allows us to refactor the procfs code, which saves a bit of
compiled space.  More importantly it isolates most of the procfs
support code into a single file, so it's easier to #ifdef it out if
the proc file system has been disabled.
