These test cases have been commented out since citext was invented, because at the time we had no nice way to deal with tests that have restrictions such as requiring UTF8 encoding. But now we do have a convention for that, ie put them into a separate test file with an early-exit path. So let's enable these tests to run when their prerequisites are satisfied. (We may have to tighten the prerequisites beyond the "encoding = UTF8 and locale != C" checks made here. But let's put it on the buildfarm and see what blows up.)
