process.py: Handle SystemExit exception to eliminate backtrace
With an invalid layer, the desired error output should be:
ERROR: The following layer directories do not exist:
ERROR: /this_path_does_not_exist
ERROR: Please check BBLAYERS in .../build-invalid-layer/conf/bblayers.conf
Instead we were met with a backtrace:
Traceback (most recent call last):
