Add -fno-sanitize=vptr for SANITIZE_UNDEFINED=ON
The UndefinedBehaviorSanitizer includes the "vptr" check. This
check, however, needs typeinfo for OCC::AccountManager because
otherwise its stub for FileManTest leads to undefined references
when linking. Adding the -frtti flag to enable run-time typeinfo
did not solve the problem. I do not know another solution, so this
commit disables the vptr check.
