[mlir] Fix build after 83d59e05b201

[aganea]

Summary

As reported in https://reviews.llvm.org/D108850#3280778

exitEarly means that no destructors should be called on LLD exit. This speeds up the exit. I've set it to true (it was false before).
disableOutput disables all stdout/stderr output. This is only used in test, when the value of ${LLD_IN_TEST} > 1.

Looks great!
