Fix wrong key type for GSet in Grease Pencil same material selection

The type of the key was changed from string to integer in 66da2f537ae8, but
the GSet was still being created for string keys.

As long as the integers stay small enough, this even kind of works on
little-endian systems, but of course it should use an integer hash instead.
