Subject: auto-removal: Ignore running kernel if attempting a reproducible
 build

If one is attempting to create a reproducible ISO image we do not want to
include the build system's kernel version, not only due to it breaking
reproducibility, but it could be somewhat misleading and/or the
wrong thing to put in this file anyway.

Closes: #857632
