Set default getenv to LAL_DATA_PATH
With environment variables needed for condor jobs specified in the .sub file, I think it is reasonable to assume that a user who has set their $LAL_DATA_PATH
wants the analysis job to use this variable. It is simple for a user to include this in their config, but I think this should not be necessary as it is likely safe to assume that a user wants to use the $LAL_DATA_PATH
they set. This MR will by default include $LAL_DATA_PATH
in the analysis job.
