quota: Make QUOTACTL config be selected by its users

Remove "depends on" line from QUOTACTL config option and rather select
the option explicitely from config options which need it. It makes more
sense this way and also fixes Kconfig warning due to GFS2 selecting
QUOTACTL but QUOTACTL not depending on it.
