checkpatch: handle casts better fixing false categorisation of : as binary 

The following incantation is triggering categorisation of its colon (:) as
a binary form, which it is not:

	return foo ? (s8)bar : baz;

Handle casts differently from types in the categoriser, allowing us to
better track (s8)bar as a value and not a declaration.
