migration/xbzrle: use ctz64 to avoid undefined result
__builtin_ctzll() produces undefined results when the argument is 0.
This can be seen through test-xbzrle, which produces the following
warning:
../migration/xbzrle.c:265: runtime error: passing zero to ctz(), which is not a valid argument
Replace __builtin_ctzll() with our ctz64() wrapper which properly
handles 0.
