env: disable aux/timesync in Plan 9 image
TestVariousDeadlines is regularly failing on
the plan9/386 builder running on GCE.
Richard Miller suspects that the failure
may be related to an issue in time measurement,
due to the clock going backward and forward.
A work around would be to disable auth/timesync
to prevent prevent the time from jumping around.
This changes fixes the Plan 9 image by disabling
aux/timesync before starting the buildlet.
Fixes golang/go#26945.
