 Testsuite: remove `-fforce-recomp` from default flags (#11980)

 There is no need for this flag anymore, since each test runs in a
 newly created directory. Removing it cleans up testlib.py a bit.

 There is a small risk that this renders some tests useless. It's hard to
 know. Those tests should have specified -fforce-recomp` explicitly
 anyway, so I'm not going to worry about it. I've fixed the ones that
 failed without -fforce-recomp.
