commitctx: treat `filesadded` more like `filesremoved`

Accumulating the filename in a list will have a negligible cost and deal with
the list of added files like the other ones will make is code cleaning simpler.
The two variable with very close name is not great, but my plan is to split most
of the code in a separated function which will make the "problem" go away by
itself.

  $ cd $TESTDIR/../contrib/fuzz
  $ OUT=$TESTTMP ; export OUT

which(1) could exit nonzero, but that's fine because we'll still end
up without a valid executable, so we don't need to check $? here.

  $ if which gmake >/dev/null 2>&1; then
  >     MAKE=gmake
  > else
  >     MAKE=make

Run each fuzzer using dummy.cc as a fake input, to make sure it runs
at all. In the future we should instead unpack the corpus for each
fuzzer and use that instead.
