Fix extroot by UUID
Extroot works fine when the target device is specified by a path. It fails however if the device is specified by UUID (the target partition gets mounted much later by hotplug hooks). This is because the blkid command is no longer compiled into BusyBox (since changeset [1]) so it's unavailable for the preinit phase. The closest bug report I was able to find is [2], although the reporting person mentions that /tmp/overlay-disabled showed up which wasn't there in my case. This patch sets PATH and LD_LIBRARY_PATH environment variables so that the blkid command installed on the target device can be used by that particular preinit script.
