rootfs_rpm: Fix rootfs generation using RPM packages

[BUG #756]

Fix bug #756.  The rootfs contains a control file /etc/rpm/platform
that specifies the default system platform, as well as patterns for
compatible architectures.  This file was not being setup properly due
to a misunderstanding of the format in a previous patch.
