poky-qemu-internal: Support NFS boots better
The image specification can now be in the form nfs-server:directory. This makes it possible to nfs-boot from servers other than the host. poky-qemu-internal will properly construct the kernel command line given such a specification. Signed-off-by: Jeff Dike <jdike@linux.intel.com>
