Fix screenrecord not saving

[MislavPukljak]

I had problem with screenrecord.
It seems like it worked, even when i stopped i get notification that recording is stopped and saved, but it was empty.

I debug it, and this is log:

After my changes:

So it uses default command bat if that fails it goes to next which fixed my problem.
If I get it right this problem is connected to NVIDIA gpu.

@ryanrhughes Seems like we could build the fallback into the gpu-screen-recorder itself?

@dhh if needed I can give it a try

@dhh gpu screen recorder supports that, see: #1830 (comment)
but in this case it's also an issue of omarchy not installing vaapi drivers, which it should do for a proper system setup, as mentioned here: #2706 fallback for cpu recording should only be done on the devices that truly dont support gpu encoding. Almost all computers support gpu encoding these days, even 14 year old laptops, if properly setup.

I made a pull request that uses -fallback-cpu-encoding option instead: #3401 and fixes other issues
