Merge #16270: depends: expat 2.2.7

0512f05 depends: expat 2.2.7 (fanquake)

Pull request description:

  Major changes in expat 2.2.7:

  * [#186](libexpat/libexpat#186) [#262](libexpat/libexpat#262)  Fix extraction of namespace prefixes from XML names;
                      XML names with multiple colons could end up in the
                      wrong namespace, and take a high amount of RAM and CPU
                      resources while processing, opening the door to use for denial-of-service attacks
  * [#227](libexpat/libexpat#227) Autotools: Add --without-examples and --without-tests

  Full changelog is available [here](https://github.com/libexpat/libexpat/blob/R_2_2_7/expat/Changes#L5).
