Tty takes a directory as long as a path may be

A terminal's directory rode inline in the spawn effect, capped at 256
bytes, so Tty in a directory of about 377 bytes said path too long. A
directory past the inline buffer now goes out of line (Pardes.spawn_dirs,
given to the host when the spawn is performed), up to the host's path
limit (4095); past that, Tty says its directory is longer than a path
may be. The effect queue stays its size.
