Adjust printf specifiers in examples code

Static analysis of example code found multiple findings of `printf` usage
where filling value is members of git_indexer_progress object. Specifier
used was for signed int but git_indexer_progress members are typed as
unsigned ints. `printf` specifiers were altered to match type.
