rust: add --check-cfg test to rustc arguments

Browse Source 
rustc will check that every reachable #[cfg] matches a list of
the expected config names and values.  Recent versions of rustc are
also complaining about #[cfg(test)], even if it is basically a standard
part of the language.  So, always allow it.
