This is a better way to prevent parallel tests from interfering with each other, as there are many ways files can be created and deleted in tests, so enforcing different file names is hard. Using $TMPDIR can also work in most cases, but 'backipskip' etc. have special defaults for $TMPDIR. Symlink runtime/, src/, test/ and README.md to Xtest_xdg dir to make tests more convenient (and symlinking test/ is required for busted). Also, use README.md instead of test/README.md in the Ex mode inccommand test, as test/README.md no longer contains 'N' char.
