relnotes: skip the test if the source repository is not readable

The test want to run the relnot extension, with the tested mercurial, on the
original repository. This is not always possible (e.g. when running with --pure
and the repository use zstd for example). So we skip the test in this case.

#require test-repo

  $ . "$TESTDIR/helpers-testrepo.sh"
  $ testrepohgenv
  $ import_checker="$TESTDIR"/../contrib/import-checker.py

Run the doctests from the import checker, and make sure
it's working correctly.
  $ TERM=dumb
  $ export TERM
  $ "$PYTHON" -m doctest $import_checker

Run additional tests for the import checker
