submodule--helper: drop unused argc from module_list_compute()

The module_list_compute() function takes an argc/argv pair, but never
looks at argc. This is OK, as the NULL terminator in argv is sufficient
for our purposes (we feed it to parse_pathspec(), which takes only the
array, not a count).

Note that one of the callers _looks_ like it would be buggy, but isn't:
we pass 0/NULL for argc/argv from module_foreach(), so finding the
terminating NULL in that argv naively would segfault. However,
parse_pathspec() is smart enough to interpret a bare NULL as an empty
argv.
