Change logs for flex source package in Focal

flex (2.6.4-6.2) unstable; urgency=medium

  * Non-maintainer upload.

  [ Ruben Undheim ]
  * debian/rules:
    - Fix build with "dpkg-buildpackage -A" by checking if directory exists
      first (Closes: #898725)

  [ Niels Thykier ]
  * debian/control:
    - Set Rules-Requires-Root (R³) to no as flex does not need/require
      (fake)root during package build.
