Revert "lib: build list_sort() only if needed"

This reverts commit a069c266ae5fdfbf5b4aecf2c672413aa33b2504.

It turns ou that not only was it missing a case (XFS) that needed it,
but perhaps more importantly, people sometimes want to enable new
modules that they hadn't had enabled before, and if such a module uses
list_sort(), it can't easily be inserted any more.

So rather than add a "select LIST_SORT" to the XFS case, just leave it
compiled in.  It's not all _that_ big, after all, and the inconvenience
isn't worth it.
