Replicating CI failures requires the developer to piece together the sanitizer flags by hand, reducing ergonomics. Fix this problem by embedding the relevant settings to the executables. Symbol resolution still needs manual intervention by setting the env variable `*SAN_SYMBOLIZER_PATH`. However, this doesn't affect any behavior.
