Restore "get rid of USE_HASH_SEED_EXPLICIT"

This reverts commit eba287cb48b881ee252ec418246375010c97a85b,
which was a revert of dd1b95f812312c85390f487887cdd55282fcd6ce.

As far as I know USE_HASH_SEED_EXPLICIT been outright broken for a long
time, and it doesnt make any sense since mandatory randomization anyway,
so simply remove it.
