resolv: Remove support for RES_USE_INET6 and the inet6 option
This functionality was deprecated in glibc 2.25.

This commit only includes the core changes to remove the
functionality.  It does not remove the RES_USE_INET6 handling in the
individual NSS service modules and the res_use_inet6 function.
These changes will happen in future commits.
