lib/dns: increase the client default timeout from 6 to 60 seconds
The 6 seconds timeout will works only on fast, stable connection.
On some environment with bad network connection, it will cause I/O timeout
during recv and this affect the whole internet connections, like
browsing.
Since the browser wait for domain to be resolved but it does
not get the response, it send another query.
The next query also got timeout again.
Increasing to 10-30 seconds also does not help on that environment.
After some tests, 60 seconds is the lower timeout limit that reduce
the I/O timeout.
It is better that we receive the response and store it to caches, so
the next query can be handled quickly, rather than timeout and retrying
with the same error.
