rules.mak: Fix module build
Module build is broken since commit c261d774fb ( rules.mak: Fix DSO build by pulling in archive symbols). That commit added .mo placeholders of DSO to -y variables, in order to pull stub symbols to executable. But the placeholders are unintentionally expanded in -y, rather than filtered out while linking. Fix it by moving the -objs expanding to before inserting .mo placeholders. Note that passing -cflags and -libs to member objects are also moved to keep it happening before object expanding.
