Subject: classes/rootfs_deb: use more reliable check for package existence

classes/rootfs_deb: use more reliable check for package existence

It turns out "apt-cache showpkg" does return some information when a
package does not exist but another package recommends it, which can
occur for empty *-dev packages; so use "apt-cache policy" with a
different line count instead.
