bitbake: bitbake: Ensure ${DATE} and ${TIME} are consistent

Due to the worker split the ${DATE} and ${TIME} variables could end up
with different values for different workers.

E.g., a task like do_rootfs that is run within a fakeroot environment
had a slightly different view of the time than another task that was not
fakerooted which made it impossible to correctly refer to the image
generated by do_rootfs from the other task.
