fix(apiserver): propagate submit user as job execuser (bug-1780)

Browse source 
modelJobToSubmit() never set job_startinfo_t.execuser when converting
a submitted job to the C struct sent to the controller/worker, so
every job ran as the worker's 'nobody' default and failed to exec
(exit 126). Default execuser to the submitting user via a new
resolveExecUser() pure helper, and free the newly allocated C string.
