Add rust_test modules.

* Temporarily append "[workspace]" to Cargo.toml and
  then run "cargo2android.py --tests --run".
* libsys_util depends on libcap in src/capabilities.rs,
  but not specified in Cargo.toml. Generated Android.bp
  needs post-editing to add libcap to link.

Bug: 140938178
Test: mm in rust projects, run out/host/.../testcases/*/*
