The binaries have a builtin check, which tests if they are executed from
the build directory, and if so, use the data files from the build
directory. Otherwise they use the datafiles from
/usr/lib/systemd/tests/testdata/

If you run the test directly from the build directory, it's reasonable
to assume that you actually want to use the data files from the build
directory as well and not the ones from the installed system.
Atm the binaries auto-detect that by encoding the build directory into
the binary.
