  test: forward real stdio calls in bss_file unit test mocks

The --wrap link option rewrites the stdio symbols of everything linked
into the test binary. In --coverage builds libgcov reads and writes the
.gcda files at process exit through fread/fwrite/fseek/ftell/fclose,
which then hit the cmocka mocks with no expectations queued and make
the binary exit with 255 after all tests have passed. Forward calls on
any stream other than the fake test pointers to the real functions.
