Convert bytes object to string in build stdout

In python3, subprocess.Popen's stdout is a list of bytes object, not string.

Bug: 117876972
Test: m -j aidegen && aidegen -m SystemUI (when it's failed to build)
confirm aidegen exists with the build error
update platform_testing/tests/example/native/HelloWorldTest.cpp to make it
unbuiltable, run "atest hello_world_test -v --host"
Confirm atest exits with proper build failure.

Trade Federation (TF / tradefed)

TF is a test harness used to drive Android automated testing. It runs on test hosts and monitors the connected devices, handling test scheduling & execution and device management.

Other test harnesses like Compatibility Test Suite (CTS) and Vendor Test Suite (VTS) use TF as a basis and extend it for their particular needs.

Building TF:

  • source build/envsetup.sh
  • tapas tradefed-all
  • make -j8
