tests: convert the 'file://\$TESTTMP' rule to an automatic substitution

The rule only triggered on non Windows platforms, even though Windows also
required an adjustment.  Automatic seems better.

The aggressive globbing in test-subrepo-svn.t was found and rewritten by the
substitution.

repo12 doesn't have any cached lfs files and its source never pushed its
files.  Therefore, the files don't exist in the remote store.  Use the files in
the user cache.

If the source repo doesn't have the blob (maybe it was pulled or cloned with
--noupdate), the blob is still accessible via the global cache to send to the
remote store.

lfs -> normal -> lfs round trip conversions are possible.  The threshold for the
lfs destination is specified here because it was originally listed in the local
.hgrc, and the global one is too high to trigger lfs usage.  For lfs -> normal,
there's no 'lfs' destination repo requirement.  For normal -> lfs, there is.

XXX: There's not a great way to ensure that the conversion to normal files
actually converts _everything_ to normal.  The extension needs to be loaded for
the source, but there's no way to disable it for the destination.  The best that
can be done is to raise the threshold so that lfs isn't used on the destination.
It doesn't like using '!' to unset the value on the command line.
