Bug 1715553 - Disable logalloc-replay check on code-coverage builds. r=firefox-build-system-reviewers,nalexander

It was already disabled for fuzzed code-coverage in bug 1695331. My
guess is that fuzzed code-coverage tripped on the extra allocations
due to the code-coverage runtime, but the code-coverage builds didn't
trip it because they also triggered an exception, which further
triggered a bug in the code with python3 (and somehow the fuzzed ccov
builds didn't trigger that). That bug effectively masked the failure.
