Pass library kind when linking native libraries.

When linking native libraries with rustc, be explicit about the
kind of native library being linked. This prevents confusion when
two kinds of one library (e.g. static/dynamic) are available in
the library search paths.

Bug: 147140513
Test: The correct prebuilt is selected when linking native prebuilts.
