tzdata: upversion to 2021e and start building

We need to install the leap-seconds.list file as
the prebuilts don't.  This file is needed for
later versions of ptp.

Verification:
- tzdata package now builds
- check built package to ensure it contains the
  leap-seconds.list file
- build-iso and make sure it contains the new rpm
- boot the iso and ensure nothing weird observed
  regarding the date
- run "export TZ=/usr/share/zoneinfo/EST5EDT" followed
  by the date command and ensure that it displays the
  correct time for that timezone
