rpmio: Disable building of the tblake2 test(s).

There is some type of a dependency fault here that can occasionally result in:

gcc: error: tblake2b.o: No such file or directory
or
gcc: error: tblake2bp.o: No such file or directory

These items are simply test cases that are not packaged, so they can be
safely disabled to resolve the dependency issue.

Upstream-Status: Inappropriate [workaround]
