Make appimage be able to work on any linux system (and some refactor of the script).

[Samueru-sama]

These changes make the appimage be able to work on any linux system, be it 15 years old or even musl distros. this is done by bundling all the libraries the nvtop binary needs + the ld-linux.so.

These changes are similar what the deploy everything mode of go-appimage does but I find it far easier to do it manually instead of fighting with the go-appimage parameters though.

Tested on Artix, Alpine (musl) and Ubuntu 20.04 (old Glibc).

The only downside is that this makes the appimage 2.4 MiB.

Also updated the readme to use 24.04 instead of 18.04, because with older versions you had to do stuff like using pip to install a newer cmake, none of this is needed anymore by building the appimage this way.

Edit: I'm linking an artifact if you want to test it, remove the .txt from the end.

Hello,

Thank you for the patch.

Right, this bundles all the libraries and the dynamic linker in the Appimage.
I can't seem to find if it's recommended or anything online but I guess it's better for distro using an older glibc or no glibc

I can probably try a build on a distro with musl and link everything statically to reduce the size.

It is fairly new practice done in go-appimage

Some examples here

If you can build nvtop statically then yeah all of this can be avoided.

Edit: even if it is not possible to build nvtop fully static, making it partially static is still ideal since that will likely still reduce the final size considerably.

For example this mpv appimage that I deploy with go-appimage, it gets built with a statically linked ffmpeg, which makes it 25 MiB, if that's not done and all the ffmpeg libs are bundled the final size ends up being ~80 MiB instead.

Sounds good, cheers.
