During a poky-image-minimal build I ran into the following error:
rm: cannot remove `/vol/1/dvhart/poky.git/build/tmp/work/atom-pc-poky-linux/poky-image-minimal-initramfs-1.0-r0/rootfs/install': Is a directory
This is caused by a missing -r (recursive) argument to rm. This patch
adds that to the rm command of rootfs_rpm.bbclass.
