Update path to beefy benchmarks
cp the python scripts from lustre instead of scp.

ssh was not working properly on multivac25.  Since this host has lustre
mounted, I decided to remove the scp command in favor of a simple cp.  This
will cause problems if a host without a lustre mount attempts to copy from
lustre.
Updated scripts for casa 4.1 testing; added 2011_0_00099_S data.
