Fix absl cached tid on Android

When compiling for Android with a minimum version less than 29, this emits calls to emulated TLS, which is substantially slower than "proper" TLS. In contrast, bionic's own gettid uses real thread local storage, so it's better to avoid this caching when the caching is more expensive than what it saves a call to.
