runtime(debian): update Debian runtime files (#14849)

* Add space in template for 'commentstring'
* Add 'comments' and 'commentstring' support to debcontrol
* debversions: Move Ubuntu releases outside of standard support to unsupported
  Although trust, xenial, and bionic are not EOL yet, their standard support period has ended.
