Subject: OPENSSL_SYS_WINDOWS is also enabled for mingw build

OPENSSL_SYS_WINDOWS is also enabled for mingw build

the test_n() in bioprinttest.c must differentiate between
MSVC runtime libc and ming runtime libc. The function
_set_printf_count_output() must be called when openssl
is linked with MSVC libc only.

Fixes #28679
