WIP: add meson build system

[elmarco]

I used Claude Code for the initial project scaffolding, but it struggled with tests and SELinux (and I struggled too, I even went down the rabbit hole and worked on proper SELinux integration in meson, although perhaps I need to revise my approach)

There is still some tests failing. Obviously testing/reviewing required.

TODO: installed-tests

@stefanberger any idea what might be wrong?

Is this supported?

yes, this was related, it was was defining it with extra quotes. thanks!
