increase TTY_NAME_MAX limit to 32
the old value of 20 was reported by Laurent Bercot as being insufficient for a reasonable real-world usage case. actual problem was the internal buffer used by ttyname(), but the implementation of ttyname uses TTY_NAME_MAX, and for consistency it's best to increase both. the new value is aligned with glibc.
