test: move TEST-08-ISSUE-2730 setup to static files and meson scripts

Unfortunately meson does not install symlinks, but copies the symlink
destination instead. So symlinks need to be created by a script.
This commit adds both symlinks in test/testsuite-08.units/ and meson
scriptlet calls. Strictly speaking, the first is not necessary, since nothing
reads stuff directly from the source tree.
