lfs: respect narrowmatcher when testing to add 'lfs' requirement (issue5794)

There's a similar test in lfs.wrapper.convertsink(), but I didn't update that
because I don't think that the sink repo in a convert can be narrow.

It seems reasonable that a narrow clone of an LFS repo may not necessarily be an
LFS repo.  The only potential issue is that LFS has a hard requirement for
changegroup v3, which that extension enables.  The use of treemanifest will
enable changegroup v3 in narrow clones, because allsupportedversions() in
changegroup.py preserves it when it sees a 'treemanifest' requirement.  But I
don't see where changegroup v3 is enabled for a flat manifest.
