bug#64977: 29.1; `auth-source-macos-keychain-search' handles :user key incorrectly

[LdBeth <andpuke@foxmail.com>]

From man security(1):

    -r protocol     Specify protocol (optional four-character SecProtocolType, e.g. "http", "ftp ")

https://www.unix.com/man-page/osx/1/security/

To test this function, first add password using:

$ security add-internet-password -s irc.libera.chat -a ldb -r 'irc ' -w 'passwd'

In emacs, use something like

(auth-source-search :user "ldb" :port "irc")

should about to retrieve the password.
