SCI32: Reduce priority of PATCHES directory for Phant2

For whatever reason, Sierra decided that the final patches would
go in the root directory for Phant2. The game disc includes
(different, older) patches for many of the same resources in the
PATCHES directory, and loading those instead makes the game not
always work quite right.
