ANDROID: fips140: split dump-section+add-section into 2 ops

It looks like llvm-objcopy regressed the ability to simultaneously dump
then re-add a section with a new name.  Prefer 2 invocations of
$(OBJCOPY); dump-sections in the first, add-section and
set-section-flags in the second. This copies the sections rather than
rename them.
