roachtest: increase timeout for network_logging to 60s

Addresses: cockroachdb#108088

The new network_logging roachtest sets a pgclient timeout of 10s
to attempt detecting deadlocks. This timeout was hit fairly easily
during the nightly runs. This is an indication that our 10s timeout
is too aggressive.

This PR changes the timeout from 10s to 60s which still achieves
the original aim without being so aggressive.

Release note: none
