The 'timeout' argument is used by 'qemuMonitorOpenUnix' only when the
'retry' argument is true. The callers of 'qemuMonitorOpen' only pass '0'
for timeout when they call it with 'retry' true and use other values
when 'retry' is false and thus ignored.
This means we can remove the argument and simply have it set to the
default value of QEMU_DEFAULT_MONITOR_WAIT.
