kernel-defaults: ensure SOURCE_DATE_EPOCH on /init

This is a follow up of 8cb13f4 which sets the right timestamp for the /init file in initramfs. The previous patch doesn't cover it as the files appear to come from a later step during compilation. CC: Alexander Couzens <[email protected]> Signed-off-by: Paul Spooren <[email protected]>
