value-range: Use int instead of uint for wi::ctz result [PR120746]

uint is some compatibility type in glibc sys/types.h enabled in misc/GNU
modes, so it doesn't exist on many hosts.
Furthermore, wi::ctz returns int rather than unsigned and the var is
only used in comparison to zero or as second argument of left shift, so
I think just using int instead of unsigned is better.
