inet: Fix threaded res_init
In a multi-threaded application where res_init() was called either
directly or implicitly, getaddrinfo() and others failed to add the
DNS search domain to hostnames.
This problem made it not possible to look up a hostname without its
domain appended.
The problem is caused by res_sync_func() overwriting the configuration
read by __open_nameservers() immediately after it is read.
The suggested solutin is to disable res_sync_func() while reading name
server configuration in res_init().
