path: expose do_git_path() as repo_git_pathv()

We're about to move functions of the "path" subsytem that do not use a
`struct repository` into "path.h" as static inlined functions. This will
require us to call `do_git_path()`, which is internal to "path.c".

Expose the function as `repo_git_pathv()` to prepare for the change.
