Define libstd dep for libunicode_width as rustlib.

libunicode_width.rust_sysroot always pulls in libstd as a dylib, which
prevents autodep from selecting the appropriate linkage type. This will
cause problems when attempting to implement static binaries.

Bug: 169434439
Test: libunicode_width no longer propagates a dependency on libstd dylib
      when one is not needed.
