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

    unit/test-ndef-parse.c: In function ‘test_ndef_single_sp’:
    unit/test-ndef-parse.c:318:33: error: field precision specifier ‘.*’ expects argument of type ‘int’, but argument 2 has type ‘uint32_t’ {aka ‘unsigned int’} [-Werror=format=]

          |                                 int       uint32_t {aka unsigned int}
