test: disable test-subrepo-git.t in python2 + chg

I am a couple of days in try to debug that at it seems minor enough with enough
other priority to simply disable it for now.

+# as a time-out error. My effort to reproduce this outside of the CI failed. The
+# test itself seems to pass fine, but never "complete". Debugging it is slow and
+# tedious. This as a bad impact on the development process as most CI run end up
+# wasting abotu 1h until that one fails.
