make startall wait up to 60 seconds for quorum

Previously we waited 10 seconds, in PVE 4 system sometimes need more
time to initialize all services so the didn't execute the startall
command even if a few seconds later cfs quorum was etablished.
This is a background process started from the pve-manager init
script, thus waiting doesn't interferes with other processes, so
wait long enough.
