test-tag: allow commit hook to also work with hg.cmd

This change allows to also use this test in MSYS on Windows with a hg.cmd file,
instead of a exemaker hg.exe only.

I'm reusing the same strategy as we did in test-hook.t: sh -c "...".

I tried specifying the hook on the command-line with --config, but failed
because we would need three levels of quoting. As a workaround, I've specified
the hook in the hgrc, like we already did in test-hook.t for several cases.
