Alexander Kanavin dea0b2d2a9 qemu-helper: depend on unfs3 and pseudo directly

The eliminates having to do extra steps (e.g. meta-ide-support)
when booting an image with a nfs mount as rootfs - startng runqemu
with a nfs mount starts to 'just work' after building an image.

#!/bin/bash

This utility extracts an SDK image tarball using pseudo, and stores

the pseudo database in var/pseudo within the rootfs. If you want to

boot QEMU using an nfsroot, you must use this script to create the

rootfs to ensure it is done correctly with pseudo.
