Send GITQSH stdout job log to a new output queue when printing

The GITQSH command logs STDOUT to a spool file using print file QSYSPRT as a base.
Overriding to the selected output queue can be done before calling the GITQSH command from your own processes as illustrated below

DLTOVR FILE(QSYSPRT) LVL(*JOB)
