startup fixes

- always use /sbin/init, even for initramfs
- mount devtmpfs for initramfs automatically in kernel space
- fix armhf for adk-test-framework
- remove mdev -s on boot, I think it is unneeded, takes very long on
  Qemu systems
- add alias for ro/rw remounts of /
- remove old /init and rc.shutdown, both unused
