Update 'rtcds lsmod' script to support Dolphin IX, replacement for open-mx

The rtcds lsmod currently checks for open-mx and Dolphin DX drivers. This needs to be update the check for Dolphin IX drivers (dis_kosif, dis_ix_ntb, dis_ix_dma, dis_irm). We are no longer using the open-mx driver).

Should also consider add-on to verify that mx_stream replacements are running (local_dc, cps_xmit)
