[PATCHv3 5/5] submodule--helper clone: lose the extra prefix option

[Stefan Beller <sbeller@google.com>]

In the rewrite from shell to C (ee8838d157761, 2015-09-08, submodule:
rewrite `module_clone` shell function in C), we never made use of the
prefix. Probably it sneaked in as module_list which was converted in the
same series had the prefix as well.
