tools/testing/selftests/sysctl/sysctl.sh: ignore diff output on verify_diff_w()
When verify_diff_w() is used we care about the result, not the verbose
output, and although we use -q, that still gives us a chatty message
about if the files differ or not. Since verify_diff_w() uses stdinput
the chatty message says whether or not "-" matches the target file, and
this just seems rather odd. Better to just ignore that messsage all
together, what we really care about i sthe results, the return value and
we check for that.
