Check workdir and input files before job submission

Use the pre-existing workdir test function, which catches permission
issues with the workdir as well as non-existence. Do this all before
we write out the job wrapper because why bother?

condor_submit doesn't benefit from this since it doesn't use
bls_add_job_wrapper (or any other common submit functions for that matter)
