New keyword arguments: 'check' and 'capture' for run_command()

If check: is true, then the configuration will fail if the command returns a non-zero exit status. The default value is false for compatibility reasons.

run_command() used to always capture the output and stored it for use in build files. However, sometimes the stdout is in a binary format which is meant to be discarded. For that case, you can now set the capture: keyword argument to false.
