localedata/locales/lg_UG: Fix some comments.

After the recent update of int_select the comment needed an update, too.
While at this, all comments in LC_TELEPHONE were moved above their
respective values because this looks better.  Some minor typos fixed.

	[BZ #21783]
	* localedata/locales/lg_UG (LC_TELEPHONE): Move all comments
	above the values, correct some of them.
