As a preparation for cross-building dracut initrds, we need to ensure
the module setup does not call external tooling (which would have to be
emulated). Further, all tool output must be consumable under sysroot as
well (e.g. paths must be resolved in the target chroot). We fix this by
replacing calls to tooling with the corresponding dracut helpers.
