[PATCH 3/5] tools/xenstored: remove the "-P" command line option

[Juergen Gross <jgross@xxxxxxxx>]

The "-P" command line option just results in printing the PID of the
xenstored daemon to stdout before stdout is being closed. The same
information can be retrieved from the PID file via the "-F" option.

Remove the redundant "-P" option.
