init: wait for asynchronously scanned block devices

Some buses (e.g. USB and MMC) do their scanning of devices in the
background, causing a race between them and prepare_namespace().
In order to be able to use these buses without an initrd, we now
wait for the device specified in root= to actually show up.

If the device never shows up than we will hang in an infinite loop.
In order to not mess with setups that reboot on panic, the feature
must be turned on via the command line option "rootwait".
