tag: use proper format for integers (-Wformat)

Properly print signed and unsigned integers.  This fixes warnings like:

    src/tag.c: In function ‘near_tag_get_tag’:
    src/tag.c:99:33: error: format ‘%d’ expects argument of type ‘int’, but argument 3 has type ‘uint32_t’ {aka ‘unsigned int’} [-Werror=format=]
