[PATCH] add more tests for t-printf and t-strerror

[pengyi]

Hi. I found in libgpg-error, the tests/t-strerror.c didn’t include some system error case; the tests/t-printf.c didn’t test the functionality of gpgrt_fwrite() which is also a common API. So I wonder if it’s possible to add more testcases in these two tests.
