Since `__sancov_default_options` and `__asan_default_suppressions` are
weak definitions, not weak references (declarations) the checks of
equality of addresses of these symbols to zero is not needed. So we can
completely remove `MaybeCallSancovDefaultOptions` and use
`__sancov_default_options` instead directly. gcc-14 emits `-Waddress`
warning to such checks.
