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.
