We would only accept "identical" links, but having e.g. a symlink /usr/lib/systemd/system/foo-alias.service → /usr/lib/systemd/system/foo.service when we're trying to create /usr/lib/systemd/system/foo-alias.service → ./foo.service is OK. This fixes an issue found in ubuntuautopkg package installation, where we'd fail when enabling systemd-resolved.service, because the existing alias was absolute, and (with the recent patches) we were trying to create a relative one. A test is added. (For .wants/.requires symlinks we were already doing OK. A test is also added, to verify.)
