[RenderScript] Set RS_PREBUILT_LIBPATH for 64bit targets.
Bug: 22796994
Bug: 22693954
This change fixes the RS_PREBUILT_LIBPATH when used with 64-bit target
devices. It also fixes an issue where the target RenderScript API is
below 21 for 64-bit compilation. In those cases, we should always
upconvert it to 21 (since that is the first available 64-bit release).
