subrepo: precisely identify the missing subrepo spec file

It isn't obvious which file is the problem with deep subrepos, so provide the
path.  Since the parsing is done with a ctx and not a subrepo object, it isn't
possible to display a path from the root subrepo.  Therefore, the path shown is
relative to cwd.

There's no test coverage for the first abort, and I couldn't figure out how to
trigger it, but it is changed for consistency.
