image-prelink.bbclass: support binary reproducibility
Conditionally support binary reproducibility in built images. If BUILD_REPRODUCIBLE_BINARIES = 1 then: 1. Do not randomize library addresses 2. Set/export PRELINK_TIMESTAMP to a reproducible value. If REPRODUCIBLE_TIMESTAMP_ROOTFS is specified, then the value will be used. Otherwise the timestamp will be derived from the top git commit.
