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.

Reference output

Since we have the same file conent on each side, we should get a limited number
of file revision (and the associated linkrev).

This these shared file-revision and the associated linkrev computation is
fueling the complexity test in this file.
