    rc.d/sendmail: Fix error with some configurations
    
    The sendmail startup script can run 4 daemons: sendmail, sendmail_submit,
    sendmail_outbound, and sendmail_msp_queue.  Of the first 3 at most one
    can be enabled.  There's a run_rc_command call for each and the ones for
    sendmail and sendmail_msp_queue run unconditionally.  For some rc
    commands this triggers warnings or errors when sendmail_enable="NO" or
    sendmail_msp_queue_enable="NO".  Since d2e7bb630b83 these errors are
    propagated and the whole script fails.
    
    Fix this by first determining which daemons are enabled, setting ${name}
    and ${rcvar} accordingly, and then always calling run_rc_command
    conditionally.
    
    Also replace ${name}.cf with sendmail.cf because ${name} isn't always
    sendmail.
