[PATCH v2 3/3] init: reuse original_git_dir in set_git_dir_init()

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

Since original_git_dir is a copy of real_path(git_dir), let's reuse it
and avoid calling real_path() more than necessary.

The xstrdup() is removed too because original_git_dir is already a copy,
and we're not going to free git_link in this code probably forever.
