unused variable errors in lib/atf/libatf-c/macros_test:use

[asomers]

Under FreeBSD stable/10 and CURRENT, the lib/atf/libatf-c/macros_test:use test fails because of unused variable errors. The easiest solution is to add references to those variables, as shown in this patch:

I think this is the same as #8, isn't it? I can't reproduce the problem any longer under amd64 current with clang.
