initramds-framework: add shutdown hook for udev
In cases where other initramfs modules need to rely on
udev running (ie in my case I have to load firmware on
a device that is slow to start) there needs to be a way
to keep it running during the lifecycle of the initramfs
but still be shut down before swith_root is called. I
added a module_pre_hook that will shut down udev before
the finish module is called.
