[scudo] Temporarily disable the build of Timer.

[Chia-hungDuan]

Summary

The placeholder was %llu while merged but it may cause problem on some
platforms that enable -Wformat. It was incorrect changed to %lu which
cause the test failure because string_utils doesn't support %lu. Will
bring this back after we fix the placeholder.
