input: copy libxkbcommon’s keysym_is_modifier()

Browse source 
When determining whether a keysym is a modifier (to skip hiding the
pointer when [mouse].hide-when-typing=yes), use the same matching
logic xkbcommon does.

This function, xkb_keysym_is_modifier() is unfortunately not part of
the public API, which is why we copy it instead.
