Fixed intrinsics inside a script group

Bug: 27439842

An RS intrinsic relies on RSExpandKernelDriverInfo.usr for the "this"
pointer to the ScriptIntrinsic object.

Need to to correctly set that field in a script execution for intrinsics.

Also fixed a bcc command-line option.

Added a test of script group with intrinsics to ImageProcessing GroupTest(native).
