Subject: [PATCH] build: Fix python files installation handling

The deprecated meson python3 module tends to end up installing only
to a python version that meson is installed for too, possibly
breaking some expectations downstream that want it installed to
a specific python3 version, that might not match what the build
machine uses for meson.
Fix it by using the non-deprecated python module and methods from it.

The python module exists since 0.46, which should be safe to require
by now. There were meson 0.50 features used already, but unnecessarily,
as the configure_file install parameter was added then, but all versions
default to `true` anyhow. However in practice this only emitted a
warning with newer meson versions and was able to build fine with older
versions too. However fix it too, so that we are now warning-free for
meson features after raising of the meson version dep.
