Makefile: Fix dependency tracking for ramstage objects 

Dependency tracking in incremental builds is currently broken for the
ramstage, due to the intermediate linking step into one ramstage.o file
per directory. The original xxx.ramstage.o files are removed from
ramstage-objs, so they don't end up in allobjs and won't get translated
into DEPENDENCIES. This patch explicitly adds them to DEPENDENCIES
beforehand to resolve the issue.

BRANCH=None
BUG=None
TEST=Built, ran 'touch src/include/cbmem.h' and built again
incrementally. Confirmed that objects dependent on the modified header
such as timestamp.ramstage.o get rebuilt correctly.
