tests: finally fix up test-fuzz-targets.t

It's been failing on my workstation for a while, since I have a new enough
LLVM that I had the fuzzer goo, but not so new that I actually had
FuzzedDataProvider. This is a better solution all around in my opinion.

I _believe_ this should let us run these tests on most systems, even
those using GCC instead of clang. That said, my one attempt to test
this on my macOS laptop failed miserably, and I don't feel like doing
more work on this right now.

blackbox should disable itself if track is empty

  $ hg --config blackbox.track= init nothing_tracked
  $ cd nothing_tracked
  $ cat >> .hg/hgrc << EOF
  > [blackbox]
  > track =
  > EOF
  $ hg blackbox
  $ cd $TESTTMP

a '*' entry in blackbox.track is interpreted as log everything

  $ hg --config blackbox.track='*' \
  >    --config blackbox.logsource=True \
  >    init track_star
  $ cd track_star
  $ cat >> .hg/hgrc << EOF
  > [blackbox]
  > logsource = True
  > track = *
  > EOF
(only look for entries with specific logged sources, otherwise this test is
pretty brittle)

when using chg, blackbox.log should get rotated correctly

With chg, blackbox should not create the log file if the repo is gone

  $ hg init repo1
  $ hg --config extensions.a=! -R repo1 log
  $ rm -rf $TESTTMP/repo1
  $ hg --config extensions.a=! init repo1

#endif

blackbox should work if repo.ui.log is not called (issue5518)
