Add TIOCPKT and TIOCSPTLCK to the Linuxolator.

Browse source 
We're very lucky, because the flags used by our TIOCPKT implementation
are the same as flags used by Linux. We can safely enable TIOCPKT,
assuming EXTPROC is not used.

TIOCSPTLCK is used by unlockpt(). Because we don't need unlockpt() in
our implementation, make this ioctl a no-op.
