fix: correctly handle kernel parameters
The kernel has an odd way to handle `"` surrounded parameters. To handle the parameters as the kernel would do, no simple shell script suffices, so a new utility `dracut-util` is introduced. Written in "C" it handles `dracut-getarg` and `dracut-getargs` as the old shell script functions `_dogetarg` and `_dogetargs` would.
