initramfs: Use KBUILD_BUILD_TIMESTAMP for generated entries
Michal Marek authored

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.
