package_rpm: remove support for DIRFILES

This was added here:
https://git.yoctoproject.org/poky/commit/?id=2f42ef8d8fb1febf28252b98884cebabc931f720

It's undocumented, untested, rpm-specific, and currently
broken, and to begin with looks like a workaround for
Tizen/smack security label conflicts elsewhere.
