REQUESTOR multiple define

[ehem]

In branch stableL, Superuser/Superuser/jni/Android.mk for LOCAL_MODULE:=su, there TWO definitions for REQUESTOR, "-DREQUESTOR="$(SUPERUSER_PACKAGE)"" and "-DREQUESTOR="$(shell cat packageName)"". The preprocessor doesn't really like this. I'd simply rip it out, but it looks like it evolved that way for some reason, so ripping it out without knowing the reason seems bad.
