Atomic reference count of binaries also in non-SMP

NIF resources was not handled in a thread-safe manner in the runtime
system without SMP support.

As a consequence of this fix, the following driver functions are now
thread-safe also in the runtime system without SMP support:
- driver_free_binary()
- driver_realloc_binary()
- driver_binary_get_refc()
- driver_binary_inc_refc()
- driver_binary_dec_refc()
