common-mk: generate-pc: add a defines field

The linter doesn't like it when you put -D into cflags.  We could
make the linter understand the AST for this specific case, but that
seems a bit error prone, so just extend the existing template to
handle defines in the same way as other build targets.

BUG=None
TEST=libbrillo pc still works
