lxc-clone: proper type for getopt_long result

While char is a signed type and should have no trouble storing a "-1" value, getopt_long() will return a value of 255 instead of -1. This has been noticed on powerpc; there's also some upstream talk about it at [1]. Change variable type from char to int, since it's also the documented use.
