Used a value of 3, it should have been a flag, #4

Need to exec() some process since linuxproc will never
signal a process named "slurmstepd"

No changes to logic

This records accounting for the job container created with a
PrologFlags option of "Contain" as added in commit
fc359331

Add PrologFlags option of "Contain" to create a proctrack container at
    job resource allocation time.
At job allocation time, a slurmstepd is spawned on every allocated
    compute node in which to place external processes (e.g. PAM
    can place ssh processes into a cgroup).
This entity is accounted for and reported by sacct as "<jobid>.extern".
Some more testing and development remain, but it mostly works.
