httpcaddyfile: Fix ordering of catch-all site blocks

Catch-alls should always go last. Normally this is the case, but we have
a special case for comparing one wildcard-host site block to another
non-wildcard host site block; and a catch-all site block is also a
non-wildcard host site block, so now we have to special-case the
catch-all site block. Sigh.

This could be reproduced with a Caddyfile that has two site blocks:
":80" and "*.example.com", in that order.
