repository: allow the global and system configs to fail loadingcmn/config-ignore-access

Common misconfigurations on the server side means that $HOME may point
to the privileged use the application was running as before it dropped
privileges. Similarly, the system config file may not always be
readable.

Allow for reading both of these configurations to fail. This fixes #2122.
