Remove lua, perl, ruby, php and gobject bindings in RHEL

gobject has always been problematic, and currently it does not work
well with the latest version of GObject.

lua, perl, ruby and php are reckoned to be unused in RHEL and pose
considerable difficulties to maintenance.  Remove them, with a view to
re-adding later if a customer complains.

(cherry picked from commit 4098de8c52789f30ac9557e934b24fb1c57020af)
