runtime: use bootstrapRand to initialize hashkey
The seed for rand is not initialized until after alginit. Before
initialization, rand returns a deterministic sequence, making hashkey
deterministic across processes.
Switch to bootstrapRand, like other early rand calls, such as
initialization of aeskeysched.
Fixes #66885.
