qa/admin/pcp-daily: small change in capturing the log

On some platforms, the log ($HOME/daily.log) was mysteriously
being truncated or over-written from the start at the init "pcp
start" step.

I suspect the "behind your back magic redirect to some other
service manager" goo, but don't have any real proof (unless this
change makes the problem go away as I move through the QA farm).
