Subject: rootfs.mk: ensure all timestamp are set to SOURCE_DATE_EPOCH

rootfs.mk: ensure all timestamp are set to SOURCE_DATE_EPOCH

Some tools doesn't support SOURCE_DATE_EPOCH (e.g. initramfs images).
Ensure all files of a root filesystem are set to SOURCE_DATE_EPOCH.
Make initramfs builds reproducible (for ramips).
