The 't/test-results' directory and its contents are by-products of the

been broken since fee65b194d (t/Makefile: don't remove test-results in
"clean-except-prove-cache", 2022-07-28).

The 'clean' target in 't/Makefile' was not directly responsible for
removing the 'test-results' directory, but relied on its dependency
'clean-except-prove-cache' to do that [1].  ee65b194d broke this,
because it only removed the 'rm -r test-results' command from the
'clean-except-prove-cache' target instead of moving it to the 'clean'
target, resulting in stray 't/test-results' directories.

Add that missing cleanup command to 't/Makefile', and to all
sub-Makefiles touched by that commit as well.

Thanks, and sorry about the breakage. I've looked this over carefully &
it fixes the edge-case you noted without making anything else that I
could spot worse.

In case it helps:

It's still a bit odd to have a "clean" that cleans up a thing it *might
have* generated, i.e. sometimes we create & use these via a Makefile
target, and sometimes by manually invoking test scripts.

But any such issues far pre-date this fix (or my commit).
