[PATCH] init: avoid superfluous real_path() calls

[René Scharfe]

Feeding the result of a real_path() call to real_path() again doesn't
change that result -- the returned path won't get any more real.  Avoid
such a double call in set_git_dir_init() and for the same reason stop
calling real_path() before feeding paths to set_git_work_tree(), as the
latter already takes care of that.
