System tomlplusplus is built against libc++ which conflicts with
libstdc++ used by GCC. While tomlplusplus can be bundled it's only
easy to do via Meson (--force-fallback-for).

Trying to build in a random directory like HOME may fail or build
something else. So, provide the context for a user who skipped
reading CMake section.
* Use plasma-polkit-agent.service rather than launching directly
This works regardless of where `polkit-kde-authentication-agent-1` is stored and also allows the service to be stopped if needed for whatever reason.
Also change instructions to refer to different init systems rather than different locations for the executable.
* forgot the period
* added back alternative paths
