release-cross: Test for unchanged native derivations

Browse Source 
These derivations do not care about the target platform, and thus should
not be affected by cross-compiling. Currently, these tests *fail*, but they
will be fixed soon by a latter PR. The release-cross job doesn't block a
channel, so this should be no problem.
