Use absolute paths for executables in condor submit files
When @sophie.hourihane posted https://git.ligo.org/computing/sccb/-/issues/993#note_593814 that lead me to bayeswave.sub which starts:
universe = vanilla
executable = BayesWave
@james-clark would it be an improvement to use the absolute paths of executables in condor submit? This should mean that the execute environment is slightly less implicitly dependent on the submission environment.
