The /usr/bin/perf script should go in a package other then the kernel
package. Otherwise it'll get removed or updated every time a linux-image
package is swizzled.

Whats a kernel related package where we could drop this script? Does
initramfs-tools make sense? udev? It hardly seems worthwhile creating a
whole new package just for this 2 line script.
