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.
