subrepo: don't attempt to share remote sources (issue5793)

Untangling _abssource() to resolve the new subrepo relative to the shared
parent's share path, and then either sharing from there (if it exists), or
cloning to that location and then sharing, is probably more than should be
attempted on stable.  Absolute subrepo references are discouraged, so for now,
this resumes the behavior prior to 68e0bcb90357 of cloning the absolute subrepo
locally.

# Since it's not easy to write a test that portably deals
# with files from different users/groups, we cheat a bit by
# monkey-patching some functions in the util module
