Remove TestApexWithJniLibs_Errors

AddFarVariationDependencies was broken, which allowed dependencies
on non-libraries to be added even though a link variation was
requested.  When AddFarVariationDependencies is fixed, attempting
to add a non-library to jni_libs results in the usual missing
variant error.

Test: none
