cmd_utils.run_command() will try to find the executable file
in the local bin/ folder firstly.
The patch also add some missing dependency files and make sure
gsi_util could run alone.
Bug: 75992357
Test: ./run_test.py
Test: './build.py setup_env',
then './gsi_util.bin check_compat --system adb --vendor adb' in
another terminal without lunch
