No longer use TZ Data artifacts under `/system/etc/tzdata_module`.

No longer generate and install Time Zone Data artifacts under
`/system/etc/tzdata_module` on the ART Buildbot. Use the
flattened Time Zone Data Module ("activated" in
`/apex/com.android.tzdata` within the chroot directory on the
device) instead.

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