Disable problematic clazy warnings

connect-non-signal and incorrect-emit are generating over one hundred warnings.
After performing a quick triage of both clazy and kdiff3 regarding these warnings.
I have determined there is no obvious fix and they are false positives.
This issue apears with clang/llvm 11 and clazy 1.8.
I don't have time to track this down further. Deactiving the offenders
until this is resolved.
