Fix mw.ustring.gmatch and patterns with '^'

The Lua manual says this:

 For this function, a '^' at the start of a pattern does not work as an
 anchor, as this would prevent the iteration.

I had interpreted that to mean that a pattern starting with '^' would
never match in gmatch. But further testing reveals that the '^' is just
treated as a literal character: string.gmatch( "foo ^bar baz", "^%a+" )
will match "^bar".
