Remove unnecessary sync calls from setup phase again.
This test runs 'sync' during the setup phase of the build. This causes the
build to pause and wait for all pending writes to complete. This step delays
the build unnecessarily. In my tests I saw this step causing the build to hang
for several minutes because other processes were writing to the disk.
This CL was previously committed in CL:2188 but was accidentally partially
reverted during CL:4664.
