[PATCH] image.bbclass: remove tmp/rootfs after image creation unless you set a variable

[Chris Larson <clarson@mvista.com>]

Set IMAGE_KEEPROOTFS to something other than the empty string to keep
tmp/rootfs around after image creation, otherwise it will be removed, as it's
not a fully functional filesystem, and causes much confusion among users as a
result.
