[PATCH] libquota: Do not build libquota when disabled

[Jan Kara <jack@suse.cz>]

Due to missing QUOTA_CMT definition in configure.in, libquota was built
(and e.g. include file was installed) even when quota support was disabled.
Fix it. Also fix help text of the configure option when we are at it.
