[build] Avoid always rebuilding bin/embedded.o

bin/embedded.o has a build dependency on bin/.embedded.list, which
gets generated automatically by the Makefile.  However, if the
EMBEDDED_IMAGE list is empty, bin/.embedded.list will never be
created, and so bin/embedded.o will be rebuilt every time due to a
missing dependency.

Fix by forcing bin/.embedded.list to be created even if the list is
empty.
