[CI] Don't run the sanitizer against the debug build

Summary:
This is causing confusion as a lock assertion will fail the sanitizers
despite the cause is unrelated. Debug build is added in D7979.

Test Plan:

./contrib/teamcity/build-configurations.py build-asan
./contrib/teamcity/build-configurations.py build-ubsan
