Update tzdata to version 2021a-2

[Brian Murray]

New upstream version affecting the following timestamp:

$region/$timezone = Pacific/Apia

Verification is done with 'zdump'. The first timezone that gets changed in the updated package is dumped with 'zdump -v $region/$timezone_that_changed' (this needs to be greped for in /usr/share/zoneinfo/). [For example: 'zdump -v Pacific/Apia'.] This is compared to the same output after the updated package got installed. If those are different the verification is considered done.

[Test Case for all releases]
1) zdump -v Pacific/Apia | grep 2021

For releases with ICU timezone data verification is done using the following with dates before and after the change:
[Test Case for releases >= 20.04 LTS]
1) sudo apt-get install python3-icu
2) python3 -c 'from datetime import datetime; from icu import ICUtzinfo, TimeZone; tz = ICUtzinfo(TimeZone.createTimeZone('Pacific/Apia')); print(str(tz.utcoffset(datetime(2021, 9, 27))))'

Additionally, an upstream update of tzdata removed the 'old' SystemV timezones, so we should ensure that they are kept in Ubuntu 20.04 LTS and earlier releases. Subsequently, these should be checked for using the following:

[Test Case for releases <= 20.04 LTS]
diff <(zdump -v America/Phoenix | cut -d' ' -f2-) <(zdump -v SystemV/MST7 | cut -d' ' -f2-)

Nothing should be returned by the above command.

tzdata (2021a-2ubuntu1) impish; urgency=medium

  * Merge from Debian unstable. Remaining changes:
    - Ship ICU timezone data files which are utilized by php and update them
      to 2021a1.

tzdata (2021a-2) unstable; urgency=critical

  * Set urgency to critical as the Samoa DST change is already effective.
  * Update Provides to tzdata-bookworm.
  * debian/control: remove Adam Conrad from Uploaders. RIP. Closes: #986954.
  * Cherry-pick patches from tadata-2021b until the upstream situation gets
    less confused:
    - 01-no-leap-second-2021-12-31.patch: No leap second on 2021-12-31 as per
      IERS Bulletin C 62.
    - 02-samoa-dst.patch: Samoa no longer observes DST.
    - 03-jordan-dst.patch: Jordan now starts DST on February's last Thursday.
