DynamicUser= enables PrivateTmp= implicitly to avoid files owned by reusable uids leaking into the host. Change it to instead create a fully private tmpfs instance instead, which also ensures the same result, since it has less impactful semantics with respect to PrivateTmp=yes, which links the mount namespace to the host's /tmp instead. If a user specifies PrivateTmp manually, let the existing behaviour unchanged to ensure backward compatibility is not broken.
