needs-restarting: Add microcode_ctl to a reboot list

commit 9f46488 upstream.

To fully update CPU microcode, a reboot is needed because the
microcode update should be applied before starting a kernel and other
process.

Therefore recommend a reboot after installing or updating
microcode_ctl package.
