rtl8192c Update Makefile and main.c
Build common symbols (rtl8192c) locally in rtl8192ce for now

This should resolve the missing symbols problems when inserting
rtl8192ce.  Long term the real issue is that common isn't being linked
in properly, and that will need to be fixed.  This band-aid should get
us working for now though (at least on the 8192ce)
