redhat/kernel.spec.template: clean up stray .hardlink-temporary files
As reported in RBHZ#2025157, the post scriptlet for the kernel-devel RPM generates thousands upon thousands of .hardlink-temporary files. This is a result of a bug in the hardlink binary (fixed in 2.38) that causes orphaned temporary files if multiple aliases for the same path are provided.
