initramfs: Use KBUILD_BUILD_TIMESTAMP for generated entries
gen_init_cpio gets the current time and uses it for each symlink, special file, and directory. Grab the current time once and make it possible to override it with the KBUILD_BUILD_TIMESTAMP variable for reproducible builds. Signed-off-by: Michal Marek <mmarek@suse.cz>
