[fuzzer] Reduce size of large.test

[nikic]

Summary

This halves the size of LargeTest, dropping time to compile this file locally from 14s to 5.5s. Hopefully this will also fix the persistent timeouts in pre-merge checks.

Note that the E macro was already unused previously.

Looks like the test is still regularly timing out. Might be good to land the patch, as unfortunately there has been no progress with respect to increasing the test timeout.
