dev: Add option to disable framebuffer .bmp dump in run folder

There is an option to enable/disable all framebuffer dumps, but the
last frame always gets dumped in the run folder with no other way to
disable it. These files can add up very quickly running many experiments.

This patch adds an option to disable them. The default behavior
remains unchanged.
