bug#71267: [TRAMP] Tramp/Emacs does not pick up PATH from login shell via Distrobox method

1. Start emacs -Q.
2. Evaluate the forms
    (require 'tramp)
    (load "path/to/tramp-2.7.1/tramp-container.el")
    (tramp-enable-distrobox-method)
3. `cd' to an `/distrobox:' location via eshell, or use find-file to
    open a file through a distrobox so that your default-directory is in
    it.
4. Observe the PATH according to Emacs
5. Then run sh -l in that distrobox (either by doing distrobox enter on
    an external shell, or via eshell). Obeserve the PATH according to
    distrobox.
6. Check the /etc/profile* files inside the distrobox to see which is
    correct.

Example, from inside emacs -Q:

    ~ $ cd /distrobox:rust-latest:.
    /distrobox:rust-latest:~ $ echo $PATH
    /bin:/usr/bin:/sbin:/usr/sbin:/usr/local/bin:/usr/local/sbin
    /distrobox:rust-latest:~ $ sh -l
    $ echo $PATH
    /usr/local/cargo/bin:/usr/local/cargo/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games
    $ exit
    /distrobox:rust-latest:~ $ cat /distrobox:rust-latest:/etc/profile.d/00-restore-env.sh 
    export PATH=/usr/local/cargo/bin:/usr/local/cargo/bin:$PATH
    /distrobox:rust-latest:~ $ 

This is especially odd, since, looking at the code, I'm seeing that the
distrobox method /should/ be calling sh with -l too, and thus getting
the profile settings. So I'm suspecting something inside emacs is
overriding that.

See the Tramp manual at (info "(tramp) Remote programs")

You need to add tramp-own-remote-path to tramp-remote-path as described there.

Best regards, Michael.

Reporting something which is not a bug is not a problem. What drives me
crazy is that you again and again remove the Cc. This makes my work
harder, because this Cc is also used to manipulate the bug status. It
takes me more time to correct this manually, than the answer itself.

Closing the bug.

Best regards, Michael.
