libnm: add some missing (transfer) annotations

All the old "const GByteArray" methods got changed to return a GBytes
instead, but since they aren't declared "const" any more, we need to
explicitly annotate them "(transfer none)".

Also, the scanner apparently doesn't recognize that an (out)
"const char **" is "(transfer none)", so annotate that in two places
too
