[Mono-dev] check for a valid system user with mono

To write software that will run on all platforms, you can not really
check if a username/password are valid, because in Linux authentication
is done with a system called PAM (and GSSAPI).

At least in PAM's case, you might not even have a password, it might
authenticate using a fingerprint reading device, or it could use
one-time-passwords.   So you really need to go through that process.
