kernel-yocto: allow patch author date to be commit date
In situations where a buid needs to be reproducible, it is sometimes desireable to use a patches author date, versus the time when it is applied. This generates a consistent hash between different patch applications. We leverage the existing KERNEL_DEBUG_TIMESTAMPS to trigger the use of a new option to kgit-s2q. This allows us to use the author date in a reproducible configuration, but disable it if we need the current time/date.
