Replaced REMOUNT with small post-test loops where possible

Browse Source 
We've been wasting a lot of test cycles thanks to REMOUNT. Using a test
define for this effectively duplicates the test, when we really just
want to run more post-test code without additional mutation.

The main reason for REMOUNT has been to save typing, which, well, is not
a bad reason, these tests involve a lot of typing...

But this is probably a hammer/nail situation. If we replace these with a
small post-test loop, we can save quite a bit of time:

  make test -j before: 5791.9s
  make test -j after:  5123.8s (-11.5%)

Some tests still use a REMOUNT define, but these should be limited to
cases where remount actually changes the test's behavior.
