Fail build gracefully if an action discovers unexpected inputs.

Blaze discovers inputs for some actions when running with some
strategies. Those actions should not discover additional inputs
when they run, regardless of the strategy they end up using.

There are now no known legitimate cases of such additional input
discovery, so we should reinstate this check and find new ones :)

We also change the failure mode to be a normal error rather than
a crash. This error does indicate a tooling issue, and a small
chance of incorrect builds, but it doesn't create such an
inconsistent state that a crash is warranted.
