Subject: [PATCH] Dockerfile: Build and use ctags v6.1.0 (upgrade from v5.9)

Changelogs: https://github.com/universal-ctags/ctags/releases

There are some function definitions that are not found by ctags v5.9.
We must upgrade to the latest release but it isn't packaged by Debian.

We only copy the ctags executable. Debian's package files are:
https://packages.debian.org/sid/amd64/universal-ctags/filelist
We drop:
 - The optscript and readtags executables,
 - The changelog and copyright files and,
 - All manpages.
