bug#33146: .authinfo.gpg not automatically loaded when using (dired) on macOS

[Christian Johansson]

Hi!

~/.authinfo.gpg seems to be loaded automatically for TRAMP sometimes but 
not always, (dired) seems to be one command that doesn't load 
.authinfo.gpg automatically.

Steps to reproduce:
1. Open emacs with src/emacs -Q
2. Open ~/.authinfo.gpg
3. Make sure this line exists: machine ftp.dlptest.com login 
dlpuserdlpuser@dlptest.com port ftp password e73jzTRTNqCN9PYAAjjn
4. Open *scratch* buffer
5. Paste: (dired "/ftp:dlpuser@dlptest.com@ftp.dlptest.com:/")
6. Run M-x "eval-buffer"
7. Notice the request for password in the mini-buffer even though 
password is already available in .authinfo.gpg

Regards
Christian
