xshared: Share a common add_command() implementation
The shared definition of cmdflags is a super set of the previous one in
xtables-arp.c so while not being identical, they're compatible.
Avoid accidental array overstep in cmd2char() by incrementing an index
variable and checking its final value before using it as such.
