Make sort {} and sort {()} equivalent

sub {} and sub{()} are equivalent.  In list context they both return
the empty list.  In scalar context they both return undef.  But sort
doesn’t seem to think so.  It croaks on sub{}.  This commit fixes that
and makes it consistent.

I left XSUBs alone, since I’m not sure how they are supposed
to behave.
