lei_to_mail+mbox_reader: fix handling of empty/bogus emails

We may be handling invalid mboxes, so just return no objects in
that case.  While "lei q" on HTTP(S) externals expects a gzipped
mboxrd, there's always a chance something else gzipped can be
sent to us.

There's also changes to lei_to_mail to better handle emails
which lack a body and/or headers (e.g. t/solve/bare.patch)
