host_alarm_handler() may be invoked as a signal handler. Previously we
did more processing in the signal handler and therefore needed
signal-safe timer code.
Today host_alarm_handler() just marks the alarm timer as expired/pending
and notifies the main loop using qemu_notify_event().
Therefore these outdated comments about signal safety can be dropped.
