test-submodule: inline resolve_relative_url() function 

The resolve_relative_url() function takes argc and argv parameters; it
then reads up to 3 elements of argv without looking at argc at all. At
first glance, this seems like a bug. But it has only one caller,
cmd__submodule_resolve_relative_url(), which does confirm that argc is
3.

The main reason this is a separate function is that it was moved from
library code in 96a28a9bc6 (submodule--helper: move
"resolve-relative-url-test" to a test-tool, 2022-09-01).

We can make this code simpler and more obviously safe by just inlining
the function in its caller. As a bonus, this silences a
-Wunused-parameter warning.
