Editor steals focus during packaging process due to Oculus SetForegroundWindow command

This also occurs in 4.13.2

This seems to be the offending line in the output log:

OCULUS: Info: [HMDState] Requested to SetForegroundWindow(1304bcll)

1. Open a BP First Person project
2. Select File -> Package -> Win64
3. Select a location and click OK
4. Cover up UE4Editor with another program such as Chrome

Result: During the cook stage the editor will steal focus of that monitor

Expected: Cook process runs in the background
