Juergen Gross c74dd50bc0 tools: use pidfile for test if xenstored is running
Instead of trying to read xenstore via xenstore-read use the pidfile
of xenstored for the test whether xenstored is running. This prepares
support of xenstore domain, as trying to read xenstore will block
for ever in case xenstore domain is started after trying to read.
