[mlir] don't match the text produced only in debug mode in Python tests

[ftynse]

Summary

Some Python bindings tests were using FileCheck to match parts of the
error description produced only in the debug compilation mode. Remove
these parts (but keep the main message) to ensure tests also pass when
running them in the release compilation mode.
