Revert "external/firebird: Try track down "Couldn't turn forced writes off" failure"

This reverts commit 128e7ce3 (plus
40b44f7e "Remove line again that was committed
in error" follow-up), now that the cause is found and addressed with
592f4f6a "external/firebird: Backport fix for
CORE-5452 causing spurious SEGV".
