[Libguestfs] [PATCH supermin] build: use a custom test driver

Use a custom test driver for running the tests: based on the test-driver
provided by automake, it adds the running time of the test in each .trs
file.

supermin-test-driver ..?

I applied this to the supermin tree to try and see how it worked,
but I can't see what it's supposed to do.  I still see the usual
`PASS:' lines in the output.

I don't know whether or not you use emacs, but:

are super annoying.  It even popped up when I opened the reply to this
email message.

Can do.

Yes, that's expected. The difference is just in what gets in the
resulting .trs files, which now have a line like:
:guestfs-time: 1
which indicates how much time each test took; this way, we can parse it
and improve the resulting XML for junit (produced by
tests/automake2junit.ml in CI).

The plan is to apply the same also to libguestfs when switching to
parallel-tests, so we can get proper test results for CI even without
$RUN_OUTPUT_FILE.

This is part of the test-driver file in upstream automake (which gets
copied in the build tree).  Should I remove them from the local copy?
