[git commit branch/0.9.33] inet: do not filter responses in res_query

[Bernhard Reutner-Fischer]

commit: http://git.uclibc.org/uClibc/commit/?id=5e40582d549b4a186de2fea9efafadd06904424c
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/0.9.33

Fixes bug #5342

res_query was silently rejecting responses against T_ANY DNS
questions.

Remove the type-filtering from res_query altogether.
__dns_lookup is supposed to return the proper stuff that you asked
for (and only that).
