compat: wrap debugstrip from core hg if it exists

Since the debugstrip command from core and strip command from the hgext.strip
extension is now the same thing, we don't have to wrap them separately. Unless,
of course, users have a copy of old (from hg 5.6 and earlier) hgext.strip
laying around that they specifically want to use, but I don't think we want to
support that use case.
