dispvm: prevent any output from qfile-daemon-dvm

This script is connected directly to calling process, so any output here
will disrupt qrexec service data. For example in case of qubes.OpenInVM
this will be prepended to modified file while sending it back to the
source VM - in case of no modification, it will override that file in
the source VM...
