Do not apply the fixup phase to ports, patching script shebangs is
infecting the ports with the packages used to prepare the port.
Do not import the package versions from the genodeSources
derivation, this breaks "nix flake list".
Make the selection of packages from buildPackages more explicit.
- Remove manifests from Dhall configurations and mix all
test inputs to generate test ROM maps.
- All loader and timer drivers are name ld.lib.so and timer_drv.
- Replace packages of multiple Genode Labs targets with functions
to build individual targets. These packages are not explicitly
specified unless they require inputs from the source ports or
extra nativeBuildInputs.
- Add support for building from Genode world repository.
