bug#67738: xinitrc function in services/xorg.scm do not handle guix-home's direcory.

(define* (xinitrc #:key fallback-session)
  "Return a system-wide xinitrc script that starts the specified X session,
which should be passed to this script as the first argument.  If not, the
@var{fallback-session} will be used or, if @var{fallback-session} is false, a
desktop session from the system or user profile will be used."
  (define builder
    #~(begin
        (use-modules (ice-9 match)
                     (ice-9 regex)
                     (ice-9 ftw)
                     (ice-9 rdelim)
                     (srfi srfi-1)
                     (srfi srfi-26))
        ...

        (define system-profile
          "/run/current-system/profile")

        (define user-profile
          (and=> (getpw (getuid))
                 (lambda (pw)
                   (string-append (passwd:dir pw) "/.guix-profile"))))

        I think we should handle '.guix-home' direcory, just like .guix-profile.

        ...

        (let* ((home          (getenv "HOME"))
               (xsession-file (string-append home "/.xsession"))
               (session       (match (command-line)
                                ((_)
                                 #$(if fallback-session
                                       #~(list #$fallback-session)
                                       #f))
                                ((_ x ..1)
                                 x))))
          (if (file-exists? xsession-file)
              ;; Run ~/.xsession when it exists.
              (apply exec-from-login-shell xsession-file
                     (or session '()))
              ;; Otherwise, start the specified session or a fallback.
              (apply exec-from-login-shell
                     (or session
                         (find-session user-profile)
                         (find-session system-profile)))))))
