tests/functional/m68k: Avoid ResourceWarning in the nextcube test

Since commit c3fd296cf7 ("functional: always enable all python
warnings") we enabled more warnings for the functional tests. This
triggers now a warning in the nextcube test:

 tests/functional/m68k/test_nextcube.py:47: ResourceWarning:
  unclosed file <_io.BufferedReader name='tests/functional/m68k/test_nextcube.NextCubeMachine.test_bootrom_framebuffer_size/scratch/dump.ppm'>
   width, height = Image.open(screenshot_path).size

Use a proper "with" context to avoid it.
