>Description:
pkg_info (usr.sbin/pkg_install/info) throws segmentation fault if non existent long option is provided.

Array struct option longopts[] in main.c isn't ended with {NULL, 0, NULL, 0} so getopt_long doesn't know where to stop and tries to read past the last element of the array.
>How-To-Repeat:
pkg_info --y
pkg_info --ble
>Fix:
Add {NULL, 0, NULL, 0} at the end of struct option longopts[] array in main.c
