Enable argv[0] tests in more places (#1061)

Browse source 
Now we do them for assimilated binaries (except on OpenBSD or XNU
non-Silicon), for XnuSilicon, and for binaries with the preserve-
argv[0] auxv flag set. We check whether to pass the argv[0] value
at the test site rather than the Child site. We move a lot of the
test initialization into Child in the non-child case, in order to
get at the pre-init value of `__program_executable_name`. Finally,
we print out info about what we are skipping.
