[gparted/ataraid: 10/12] Recognise ATARAID members started by dmraid (#75)

[Mike Fleetwood <mfleetwo src gnome org>]

commit 3c6f0ef23720e19a236c0f7b8cd4e4d10539e133
Author: Mike Fleetwood <mike fleetwood googlemail com>

    Recognise ATARAID members started by dmraid (#75)
    
    This is not strictly necessary as members are already recognised using
    blkid since this commit earlier in the sequence "Recognise ATARAID
    members (#75)".  However it makes sure active members are recognised
    even if blkid is not available and matches how file system detection
    queries the SWRaid_Info module.
    
    Closes #75 - Errors with GPT on RAID 0 ATARAID array
