When running toltecctl reenable with rm2fb not starting correctly.

The errors come from here https://github.com/toltec-dev/toltec/blob/stable/package/display/package#L65-L74

This is specifically when running on an unsupported version. While we don't support it, I do think we should handle the error better and not leave rm2fb enabled if it failed to start.

@Jayy001 Now that #686 has been merged, have you had a chance to see if this is still an issue?
