bind: Update to version 9.16.22

- Update from 9.11.32 to 9.16.22
- 9.11 is an ESV (Extended Support Version) that will go EOL in December 2021
  9.16 is the replacement ESV whose EOL is not yet defined but will be at least 4 years
   so should be supported until at least March 2024 as the 9.16 branch was started in 2020
- Update rootfile
- libuv is now required both to build the bind libraries and for the running of the
   utilities.
- Changelog is difficult to define here as this is a change of branch from 9.11 to 9.16
   both of which have been running in parallel. However all the changes from the start of
   9.16.0 can be found in the CHANGES file in the source tarball.
- nslookup, host and dig utilities tested out by installing this on a vm testbed. All
   these utilities worked as the previous version
   nsupdate was not able to be tested other than confirming that running nsupdate
   opened an interactive session. This utility would be good to be tested by someone
   familiar with how to run it.
