Increase default boostrap time in test-network.sh to 30 seconds,
for larger networks like bridges+ipv6+hs.
This avoids the failure-hiding issues inherent in the retry approach
in #16952.
# Sleep some, waiting for the network to bootstrap.
# TODO: Add chutney command 'bootstrap-status' and use that instead.
