As submodules have working directory and their git directory far apart
relative_path(gitdir, work_dir) will not produce a relative path when
git_dir is absolute. When the gitdir is absolute, we need to convert
the workdir to an absolute path as well to compute the relative path.
(e.g. gitdir=/home/user/project/.git/modules/submodule,
workdir=submodule/, relative_dir doesn't take the current working directory
into account, so there is no way for it to know that the correct answer
is indeed "../.git/modules/submodule", if the workdir was given as
/home/user/project/submodule, the answer is obvious.)
