[tz] Downstream use of 2021c

What I've done for Python's tzdata so far is that I released 2021.2 as
2021a+Samoa+Jordan, then I immediately made a 2021.2.post0 release that
is just a straight repackaging of 2021b. In Python's system it's not too
hard to explicitly rule out a version (i.e. depend on "tzdata !=
2021.2.post0"), so I figured this was the "best of both worlds" approach.
I haven't repackaged 2021c yet because it seems like most of the major
bugfixes in 2021c are fixes to regressions that happened between 2021a
and 2021b, so anyone who is affected by these can use tzdata !=
2021.2.post0, and I didn't want to continue maintaining this two-track
versioning system (since blacklisting a single revision is not much of a
pain, but blacklisting a sequence of revisions is a lot more annoying).
If the removal of "most" of the controversial link changes is enough for
the crowd upset by the changes in 2021b, it would certainly be nice to
go back to just automatically cutting binary releases from the release
