Add vulkan-headers and rpm-tools as dependency

[RoonMoonlight]

Tested with Arch Linux (Container version), but without these two packages the compilation fails.

vulkan-headers make sense (we don't depend on it directly but I think KWin started requiring them).
But could you elaborate what exactly fails without rpm-tools (e.g. build logs)? I don't really see any reason why those would be required.

When I do this on Bazzite with Arch container:

cpack -V -G RPM

This happened without rpm-tools in Arch container

I'm not too familiar with Bazzite but wouldn't you usually use a Fedora based container that has the RPM stuff already? I don't think this is common enough to be in the documentation section for Arch Linux (which I'd say is mostly meant for the native install path)

[RoonMoonlight]

Will be working on it soon to mention the rpm compilation to recommend fedora
