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.
Fixes issue #777
