The max path length for unix sockets is pretty small (108, see man 7 unix). If 'make check' is run from a directory that exceeds this, one of the tests will fail, and in such a way that requires manually editting the test to determine why. There are certainly other ways to handle this, but I've chosen just to skip the offending test if we will exceed the length limitation. v2: Drop bashism, use test infrastructure to warn and skip
