Update gfx.kart hash

CONS_Printf calls CON_Drawer during startup, thread
collision stuff.

Fixes some wild behavior when a lot of hole punching
requests are coming in.

This reverts commit 5ec44ba3, reversing
changes made to 4c5d69b7.

Doesn't prevent it from happening later if the rules weren't successfully fetched, though.

Notably caused by a difference in behaviour between Software and GL that was already resynchronised in the 2.2 codebase.

Seems to be a regression in internal too. Requires more analysis on behaviour in the 2.2 engine, but essential for maintaining compatibility in 2.1 (such as with Opulence wobbly carpet).
