Add some ptyfs tests.

Note: I'm not adding these to the build yet, since they depend on
some other other cleanup I might get done only after the weekend.
Even so, t_nullpts serves a simple example of how to repeat the
crash described in PR kern/43456 (just remove "rump_sys_" from the
calls and it should compile and you should get a host kernel panic
instead of a coredump).
