Remove the use of version scripts with header-abi-linker.

Version scripts were earlier used as a symbol map, primarily for llndk
libraries. Since they do have stub libraries which contain symbols, we
shall use them instead, to internally form symbol maps in
header-abi-linker.

Test: mm -j64 in bionic/libdl, header-abi-linker gets invoked with
      -so <so-file> rather than -v <version-script>
