vasnprintf, vasnwprintf: Make '0' flag handling more ISO C compliant.
* lib/vasnprintf.c (VASNPRINTF): When doing the padding ourselves,
ignore the '0' flag if a precision is specified and the conversion is
one of d, i, o, u, x, X, b, B.
* tests/test-vasnprintf-posix.c (test_function): Update expected results
accordingly.
* tests/test-vasprintf-posix.c (test_function): Likewise.
* tests/test-snprintf-posix.h (test_function): Likewise.
* tests/test-sprintf-posix.h (test_function): Likewise.
* tests/test-vasnwprintf-posix.c (test_function): Likewise.
