    Stop nicing external commands run by the DMRaid module (#788007)
    
    No other commands run by GParted are niced, so stop nicing commands run
    from the DMRaid module.
    
    I think nicing of possibly long running file system modification
    commands would have made virtually no difference because "nice -n 19"
    lowered the CPU priority, but such command would be I/O bound.
    
    History:
    
    Nicing of file system modification commands was added by this commit
    from 2006-08-21:
        82e6f6b132fd7960950a71a2af2db6ef93fde583
        added nice -n 19, so that all extensive filesystem operations will be
    
    Nicing of DMRaid operations was copied into the DMRaid module when it
    was added here in 2009-03-14:
        5865c92dc054dc87739e6a70b21f91825f214c9e
        Added new class for dmraid support
    
    Nicing was removed from file system modification commands with this
    commit from 2013-02-22:
