meson: Move the BUILD_DATE/TIME setup to configure time. 

By having it as a custom_target with build_always, every "ninja -C
build" would rebuild Xorg for the new date/time, even if the rest of
Xorg didn't change.

We could build the rest of Xorg into a static lib, and regenerate
date/time when the static lib changes and link that into a final Xorg,
but BUILD_DATE/TIME is such a dubious feature (compared to including a
git sha, which is easy with meson) it doesn't seem worth the build
time cost.
