Update docker-with-sudo macro to also work on remotes

[SnowDiver]

I updated the macro as I wanted to run docker command on a remote wtih elevated privileges. I used the function '"tramp-file-name-with-sudo" to update the default-directory to the sudo variant which works for local and remote paths.

Seems you forgot a )

Also indenting looks weird. Please verify.

Ah sorry, that's what you get from using the browser :/
I updated it now.

Problem:

CI byte-compile fails with:
Error: the function `tramp-file-name-with-sudo' is not known to be defined.

Solution:

• Tell the byte-compiler the symbol exists:
  (declare-function tramp-file-name-with-sudo "tramp")
• Guard runtime use so Emacs without tramp doesn't break:
  wrap the call with (fboundp 'tramp-file-name-with-sudo) and fall back to default-directory.

Suggested patch:

(declare-function tramp-file-name-with-sudo "tramp")

(defmacro docker-with-sudo (&rest body)
  (declare (indent defun))
  `(let ((default-directory (if (and docker-run-as-root
                                     (fboundp 'tramp-file-name-with-sudo))
                                (tramp-file-name-with-sudo default-directory)
                              default-directory)))
     ,@body))
