fsck: warn about symlink pointing inside a gitdir
In the wake of fixing a vulnerability where `git clone` mistakenly
followed a symbolic link that it had just written while checking out
files, writing into a gitdir, let's add some defense-in-depth by
teaching `git fsck` to report symbolic links stored in its trees that
point inside `.git/`.
Even though the Git project never made any promises about the exact
shape of the `.git/` directory's contents, there are likely repositories
out there containing symbolic links that point inside the gitdir. For
that reason, let's only report these as warnings, not as errors.
Security-conscious users are encouraged to configure
`fsck.symlinkPointsToGitDir = error`.
