Add CleanSpec for TZ Data artifacts under `/system/etc/tzdata_module`.

These artifatcs are no longer used on ART Buildbot's devices, as they
now use the Time Zone Data APEX.

(That these files are still used on Golem though, but the build system
will regenerate them).

Test: ART chroot-based on-device testing using the master branch (with
      `TARGET_FLATTEN_APEX` set to `true` before building).
