Bugfix: Avoid numeric overflow when validating transaction value ...

It's possible for `tx.value` in the transaction to have a deliberately
constructed large 256-bit value, such that adding `gasLimit * gasPrice` to it
overflows to a small value.

Prior to this patch, the code would allow such a transaction to pass
validation, even though such a large transfer cannot be valid.
