Greasemonkey: use UrlPatterns for match directives

The greasemonkey `@match` directive is used to match urls against
chromium url patterns (as opposed to `@include` which treats its
argument as a glob expression). I was using fnmatch for both here
because I am lazy and knew someone else was going to implement chromium
url patterns for me eventually. Now it is done and I should switch to
using them instead. The most common failing case that this will fix is
something matching on `*://*.domain.com/*` because it wouldn't match
the url with no subdomain.

This codepath is only used on webengine 5.7.1 and webkit backends.
