rpm: Fix FILES_${PN}
In a recent commit, the FILES expression for rpm accidently moved a
large portion of rpm-build into rpm:

Since rpm-build requires perl, this caused a number of build failures
when the rpm-build package was attempted to be used since it references
/usr/bin/perl. This commit restores the previous contents of the rpm
package.
