[Test/bmp2png]: Fix -Werror errors after warnings level increase

This fixes the following error, encountered with gcc 10.2:

| ../../../../../../workspace/sources/nnstreamer/tests/bmp2png.c: In function 'save_png_to_file':
| ../../../../../../workspace/sources/nnstreamer/tests/bmp2png.c:95:16: error: variable 'status' might be clobbered by 'longjmp' or 'vfork' [-Werror=clobbered]
|    95 |   register int status = -1;
|       |                ^~~~~~
| cc1: all warnings being treated as errors
