[drogon] fix drogon_ctl command not found error

[hexorer]

The drogon library provides a cmake function drogon_create_view that uses its drogon_ctl too. but it uses drogon_ctl by PATH env instead of using cmake's find_program. this causes error when drogon_create_view is being used by dependee.

This patch fixes that to use find_program.

I've also additionally prefixed patches by 001... numbers.

• Changes comply with the maintainer guide
• SHA512s are updated for each updated download
• The "supports" clause reflects platforms that may be fixed by this new version
• Any fixed CI baseline entries are removed from that file.
• Any patches that are no longer applied are deleted from the port's directory.
• The version database is fixed by rerunning ./vcpkg x-add-version --all and committing the result.
• Only one version is added to each modified port's versions file.

This is still a problem with the latest dragon builds in docker.

Use Ubuntu 20.04 LTS as a base image

FROM ubuntu:20.04
