base: fix transportd fail to monitor dtmd [#3170]
- Due to #3167 fix, sometimes get node unexpected reboot due to
transportd fail to monitor dtmd. This is timming issue if dtmd
create pid file with 0640 then chown to opensaf user. Then transportd
see pid file right after created but fail to read it.
- Keep old permissions, only change permissions after chown done.
Also retry open fifo file if no such file error.
