    makefs/zfs tests: Run in parallel
    
    Use the script PID as a pool GUID.  This way, tests running in parallel
    will have pool GUIDs that won't collide, and the tests no longer need to
    be serialized.
    
    MFC after:      1 month
    
    (cherry picked from commit 68dc9c6b8ef86caef3962cc9177bb21d8f38b0ed)
