Improves compatibility with AddressSanitizers
Address sanitizers is expecting shared objects loaded without the flag RTLD_DEEPBIND. This can be achieved by setting the environment variable AFB_NO_RTLD_DEEPBIND to the value 1 (exactly). This implies that the binder takes care of not clashing the namespaces by defining the symbol afbBindingV3root in both environment: the binder and the bindings.
