zink: fix gpl lib hashing

Browse source 
this was including the generated tcs bits, which was likely to be wrong
and thus break optimal key hashing, requiring more pipelines

it also wasn't setting the optimal key value correctly during precompile,
which meant the wrong hash value was used and the precompiled libs were never
actually accessible
