*/build.prop files are now loaded much earlier than before; from 'on post-fs' to the time when the property service is started which is before init starts the action loop. This ensures that all processes that are launched by init have a consistent view of system properties. Previously, the processes that started before 'on post-fs' were initially with the small number of sysprops loaded from */default.prop and then suddenly get additional sysprops from */build.prop while they are executing.
