test-subrepo: demonstrate problems with subrepo sharing and absolute paths
This affects remote paths in .hgsub, as well as clone pooling from a remote
source.
For reasons unknown, there are stability issues with the relative-path.t tests.
If run as a single test, it is stable. If run with --loop, or with -jX for X>1,
the hash of the parent repo changes. I'm seeing this on both Windows and Fedora
26. I added an `hg log --debug`, and the manifest hash changes, but I have no
idea why.
