[PATCH 08/20] submodule--helper: move "resolve-relative-url-test" to a test-tool

[Ævar Arnfjörð Bjarmason <avarab@xxxxxxxxx>]

As its name suggests the "resolve-relative-url-test" has never been
used outside of the test suite, see 63e95beb085 (submodule: port
resolve_relative_url from shell to C, 2016-04-15) for its original
addition.
