Do not specify LOCAL_REQUIRED_MODULES for libbc.so

Bug: http://b/28866258

libclcore*.bc and libcompiler-rt.so are instead listed as required
modules for libRS.

Test: - Build all topics in this CL
      - RsTest (including the 32-bit ABI) and CTS tests pass on x86 and
        x86_64 emulators and Angler.
