build(fiptool): add object dependency generation

Browse source 
The object target in the fiptool Makefile only depends on the
corresponding source file so it won't rebuild the object, if a header
file used by the source file is changed.

To make it rebuild the object file for both source and header file
changes, a dependency file will now be generated for each object and
included in the Makefile.
