[ovs-dev] [PATCH] ovs-lib: Do not tee the o/p in case of strace.

[Gurucharan Shetty]

Looks like running the OVS daemons with strace option enabled
will block if tee is used to redirect the output. We use tee
to log the output of ovs-ctl to ovs-ctl.log

This patch disables the startup script logging when we run the
OVS daemons with the strace option.
