[PATCH trivial] ui/gtk: Fix callback function signature

[Filip Hejsek]

The correct type for opaque pointer is gpointer,
not gpointer * (which is a pointer to a pointer).

This fixes a small mistake in callback function signature. The mistake
didn't cause any actual problems, so this patch is just code cleanup.
