fingerprint: Sync filesys after copying fw files to DUT
We have seen cases where the fw files are intact when first copied to
DUT, but becomes empty (size is zero) after a reboot, so do a sync
after copying files to DUT.
BUG=b:171238402
TEST=flash new OS image on lab DUT, then run firmware_Fingerprint.RDP0
(on Morphius) => Pass
