Build opencv libs with videoio module support (Linux)

[kalwalt]

This PR add videio support to the build script and consequently after merged i will make a new release with the new libs.
Enabled plugins for V4L, ffmpeg and gstreamer. Without them you can't display a video.
No changes to the Emscripten build.
@Algomorph This PR also will integrate changes from #7 into the main branch.
I added a bunch of improves to the action github script to address some minor issues.

The action github fails with:

./build.sh linux
./build.sh: line 213: pcregrep: command not found
cat: write error: Broken pipe
Error: Process completed with exit code 127.

Before this, it not happened, probably changed something in the ubuntu image? I will add the installation of pcregrep and i will upgrade actions/checkout@v3, actions/setup-node@v3 to v4.
