Addd RenderScript default implementation to Angler device.mk

Bug: 37035983

  - OVERRIDE_RS_DRIVER is moved from libRS_internal to the default
    implmentation. In order for GPU driver to work on legacy devices,
    the default implementation needs to be part of PRODUCT_PACKAGES.

Test: mm
Test: CTS tests pass on Angler, and confirm GPU driver is
      working.
