fix: patch mistaken overrides

[erights]

Patch mistaken overrides.

These were the overrides that prevent us from changing

agoric-sdk/packages/agoric-cli/test/test-main.js

Line 4 in 09b239d

import '@endo/init';

to

import '@endo/init/debug.js';

at
#5567
since debug.js also sets overrideTaming to 'min' as it should, in order to catch such problems.

Why does enumerable: true cause the problem?

Approving since I assume you have a good answer : )

Clarified by adding

+            // enumerable: true would accurately preserve the behavior of the
+            // original assignment, but I'm guessing that was not intentional.
+            // For an actual error subclass, this property would not
+            // be enumerable.

to all the relevant enumerable: false cases.
