l2md: don't panic on umatched git objects during repo walk

During repo walking, revparse expects to find objects based on the
oid:"m" specification, but public-inbox encodes some specific objects
(e.g. spam) differently, and that causes the walk to bail out. Fix by
skipping all objects that don't match the default mail specification.
