vasnprintf-posix: Fix crash in narrow %lc directive (regr. 2023-03-21).
* lib/vasnprintf.c (VASNPRINTF): Negative results of local_wcrtomb can
now occur; handle them.
* tests/test-vasnprintf-posix.c (test_function): Test %lc directive with
a wint_t argument that is not a valid wide character.
* tests/test-snprintf-posix.h (test_function): Likewise.
* tests/test-sprintf-posix.h (test_function): Likewise.
* tests/test-vasnwprintf-posix.c (test_function): Likewise.
* tests/test-vasprintf-posix.c (test_function): Likewise.
