tests: pacify GCC 5.1's stricter printf checking

* tests/test-dirname.c (main):
* tests/test-getaddrinfo.c (simple):
* tests/test-getlogin.c (main):
* tests/test-getndelim2.c (main):
* tests/test-inttostr.c (CK):
* tests/test-md5.c (main):
* tests/test-read-file.c (main):
* tests/test-sha1.c (main):
Fix mismatches between printf format and value signedness.
* tests/test-inttostr.c (FMT, CAST_VAL, V_min, V_max):
Remove, as CAST_VAL always returned a value of type uintmax_t.
