Wrapper around a build action that should only be executed in release mode.
The mode is defined via an environment variable DART_BUILD_MODE.
The arguments to the script are:
only_in_release_mode.py files... -- command arguments...
If mode is not 'release', the script will create the files listed
before --. If mode is release, the script will execute the command
after --.
