Add rust_test modules and TEST_MAPPING.

* Temporarily append "[workspace]" to Cargo.toml and
  then run "cargo2android.py --tests --run".
* Manually add defaults to limit build host.
* Manually add TEST_MAPPING to select all rust_test modules.
* 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: atest --include-subdirs --rebuild-module-info external/crosvm
