Subject: resolv: Reset defdname before use in __res_vinit [BZ #19369]

Resetting defdname (default domain name) before use in __res_vinit
ensures that the default domain name is correctly set to a default
value when it is not set by the LOCALDOMAIN environment variable or
the "domain" or "search" parameters in resolv.conf

Tested using the steps from:
