On OpenBSD _JBLEN is the number of slots (of type long) in jmp_buf.
We don't need 256 slots, so change it to 32 which leaves us with a few
spare slots and is probably what was intended.
This fixes building emacs which does some insane setjmp(3)/longjmp(3)
stuff and gets upset when jmp_buf is 2048 bytes.
