test: Add tests for handling symlinks with systemd-sysext

Browse Source 
When we now allow following symlinks inside a --root= we should also
test that it works in various cases from simple relative and absolute
symlinks to .v being a symlink itself or its contents, both for
directory and for .raw image extensions. While at it, also add a simple
test for .v without symlinks which wasn't there for direct usage of
systemd-sysext.
