Description of problem:
Applications that use consolehelper can be configured to ask for the user
password or root password. userhelper would show a prompt like "Password for
userfoo" accordingly.
The problem is that PAM now uses i18n strings, and userhelper fails to find the
literal string "password" in the PAM prompt and chooses to use the string as is
instead of the "Password for %s" one. So, one cannot tell from the dialog box
which user's password is being requested.

Version-Release number of selected component (if applicable):
usermode-1.91-1

How reproducible:
Always

Steps to Reproduce:
1. Set a locale different from english
2. Use a consolehelper application which asks for the user password
3. See the dialog box: it will display a bare prompt like "Password" (in the
selected language) instead of "Password for <username>".
  
Actual results:
Confusing password prompt

Expected results:
Password prompt showing which password is being requested

Additional info:
userhelper.c:564
            case PAM_PROMPT_ECHO_OFF: {
                char *noecho_message;

                /* If the prompt is for the user's password,
                 * indicate the user's name if we can.
                 * Otherwise, just output the prompt as-is. */
                if ((strncasecmp(msg[count]->msg, <--- this fails
                         "password", <-- non i18n string
                         8) == 0)) {
                    noecho_message =
                        g_strdup_printf(_("Password for %s"),
                                user);
                } else {
                    noecho_message = g_strdup(msg[count]->msg); <- we get this
                }

Same also happens in line 848.
