ld.mc uses libcompier_rt and libRSDriver from the vndk-sp directory

When ld.mc links the compiled bc, it now correctly uses libcompiler_rt
and libRSDriver from the vndk-sp directory. This is because when the bc
is loaded inside the app process, it is provided with the libs in
vndk-sp directory.

Bug: 62848943
Test: Renderscript app (e.g. CameraScript) runs well.
Test: logcat | grep ld.mc shows /system/lib/vndk-sp/libcompiler_rt.so
and --library-path=/system/lib/vndk-sp
