Zero out wallet master key upon lock
When an encrypted wallet is locked (for instance via the
RPC `walletlock`), the docs indicate that the key is
removed from memory. However, the vector (with a secure
allocator) is merely cleared. This allows the key to persist
indefinitely in memory. Instead, manually fill the bytes with
zeroes before clearing.
