bdev_raid.sh was using configuration file (bdev.conf.in) made for blockdev.sh. Changes in that config file affected the raid tests. Since the test actually only used two malloc devices as raid bases, switching to RPC makes it simpler clearer to understand what is used in tests. Additionally making raid tests standalone from blockdev.sh.
