configure.ac: Make BUILD_{DATE, TIME} respect SOURCE_DATE_EPOCH if set
Whilst working on the Reproducible Builds effort [0], we noticed that
xorg-server could not be built reproducibly. One reason is because it
embeds a "current" build and date time.
This should be compatible with both GNU and BSD date(1).

v2: Fix change in Y-M-D format that broke the build.
