S3_2 rscompat: Stop relying on ERM_CLEANPOLLUTION/ERM_CLEANFALLOUT
S3_2 rscompat.c expects values ERM_CLEANPOLLUTION and ERM_CLEANFALLOUT to be available, for it to temporarily assign those values to the extra loaded from a 3.1 ruleset. This won't be the case with #48135
Patch attached. For S3_2 only.
