gutils: Fix deliberate-leak code in g_reload_user_special_dirs_cache()

It seems it wasn’t behaving as advertised: it was freeing all the old
string values unless they were strcmp-equal to the new ones, in which
case the new ones were discarded.

What’s actually documented is that the old values are always leaked,
unless they’re strcmp-equal to the new ones.

Adjust the code to match the documentation. A unit test will be added in
a following commit.
