Log Message:
-----------
terminal: log TIOCGPTPEER failure less alarmingly

This is not a fatal error and the fallback codepath is equally safe.
When we use TIOCGPTPEER we're using a stashed fd to the container's
devpts mount's ptmx device and allocating a new fd non-path based
through this ioctl. If this ioctl can't be used we're falling back to
allocating a pts device from the host's devpts mount's ptmx device which
is path-based but is not under control of the container and so that's
safe. The difference is just that the first method gets you a nice
native terminal with all the pleasantries of having tty and friends
working whereas the latter method does not.
