Remove the corresponding entries from tramp-methods. Something like
(setq tramp-methods (delete (assoc "sudo" tramp-methods) tramp-methods))
Same for "su", and "sudoedit" (once it is added to Tramp). However,
"sudoedit" is intented to just read a file, and save the respective
buffer. No interactive shell under the hood, no backup files, no remote
processes - nothing else but file reading and buffer saving. The idea is
to use a proper emacsclient call for this.

Tramp manifests itself via autoloads. They are still active when running
'emacs -Q'.
Tramp does already some actions when it detects that emacs has started
with "-Q". For example, it doesn't read the persistency file
"~/.emacs.d/tramp". We could extend this mechanism.
