Fix GitHub actions

Our build was flaking due to ETXTBSY errors running multiple redbean
instances in parallel. This is due to the StoreAsset() support which
seems to cause enough problems it's worth making a *breaking change*
turning it off by default for now. There's a new -* flag, to restore
redbean's old self-modifying behavior.
