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

[LdBeth <andpuke@foxmail.com>]

I think it is possible to use cl-left to redefine
`auth-source-macos-keychain-search-items' to avoid calling external
security command and just check the argument passed to
`call-process'.

Something like:

(cl-letf (((symbol-function 'call-process) (lambda (&rest r) (print r))))
  (auth-source-search :user "ldb" :port "irc"))

("/usr/bin/security" nil t nil "find-internet-password" "-g" "-a" "ldb" "-r" "irc ")

("/usr/bin/security" nil t nil "find-generic-password" "-g" "-a" "ldb" "-s" "irc")
