Very occasionally we see errors in eSDK testing on the autobuilder where the task
hashes in the eSDK don't match what was just built. I was able to inspect one of
these build directories and noticed that the bb_unihashes.dat file in the eSDK
was zero sized. Whilst inspecting the code to understand the cause, I noticed that
updated hashes are not saved out in subsequent updates of the values in the rehash
process.
Add a missing sync call to ensure this happens.
