url_matcher: Treat FQDN hosts as if they were relative.

This changes URLMatcher to not make a difference between
fully-qualified and relative URLs. Patterns that specify
fully-qualified host names now also match the corresponding relative
host name in URLs and fully-qualified host names in URLs now match
patterns that use relative host names.
