executor: bump on FreeBSD the maximum number of tun devices to 256 (#2956)
syz-execprog now uses twice the number of CPU cores as the number
of processes. Each process might use a tun device. So bump the
maximum number of tun devices to the maximum of 256, which allows
syz-execprog to run with default settings on systems with up to
128 cores.
