test/vhost: remove unnecessary lines from JSON result file

Browse Source 
There is a lot of extra lines at top of the output file
in case fio is used in client-server mode and with json
output mode. These lines make it resulting JSON file
not possible to parse.
Remove this lines so that the JSON file is ready to
be used in any later parsing functions.
