If access failed, e.g. due to insufficient permissions, don't confuse
the user by reporting an API mismatch.
This is a minimal improvement to target issue #802. As, if access is
restricted to a group, that group is known in Meson, it would even be
possible to report that group in the error message. But, that would
require converting ratbagd.py to a template or finding some other way to
inject that information at build time.
