fix(freebsd): incorrect constant type from ttycom.h

[nanpuyue]

ref: #493

the value and type of the constant are obtained by executing the following script

ttycom.sh:

#/bin/sh

cat <<EOF
#include <stdio.h>
#include <sys/ttycom.h>
#include <sys/time.h>
#include <termios.h>

void main() {
EOF

grep -o TIOC[A-Z_]* /usr/include/sys/ttycom.h | sort -u |\
 xargs -I{} echo '    printf("pub const {}: u%lu = 0x%lx;\n", sizeof({})*8, {});'

echo '}'

./ttycom.sh > main.c
clang main.c
./a.out

LGTM. These should all be unsigned long in Rust, because while in C they're defined typelessly, their main function is to be passed to ioctl, which expects an unsigned long.
