ci/release: install dependencies on Linux

[MrAnno]

This adds Linux dependencies to the release binary, and also clarifies that these binaries are for glibc 2.31 or higher.

Static linking would have been better, but Ubuntu does not provide fPIC static libraries for Lua, so I ended up implementing this terrible dependency installation method.

TODO: check if we are allowed to upload these binaries without rebuilding them from source

Any redistribution of modified versions of Ubuntu must be approved, certified or provided by Canonical if you are going to associate it with the Trademarks. Otherwise you must remove and replace the Trademarks and will need to recompile the source code to create your own binaries.

I'm not sure our usage counts as a "modified version of Ubuntu".

As far as I understand this sentence is about when somebody wants to create a new Linux distribution using Ubuntu sources. I don't think using one of the libraries in a static linkage (particularly in a GPL license code) is something Canonical worries about.
If you are ready with this PR I can merge it. If they have any objections to it, I can remove it later.

[MrAnno]

Dynamic libraries are packaged in this PR with an ORIGIN runpath trick instead of linking statically (I ran into problems with that due to the non-PIC Lua static lib that is supplied by Ubuntu).

But either way, I think we are OK.
