Do not unconditionally wait for read events on the pty associated with a
vm console. Instead, wait for the controlling end of the pty to become
writeable, which implies that the slave end is connected. A recent
change to the kqueue pty implementation caused vmd to hammer the log due
to constantly hitting EOF while reading from the pty since the slave end
was disconnected.
