exclude: do not respect symlinks for in-tree .gitignore
As with .gitattributes, we would like to make sure that .gitignore files
are handled consistently whether read from the index or from the
filesystem. Likewise, we would like to avoid reading out-of-tree files
pointed to by the symlinks, which could have security implications in
certain setups.
We can cover both by using open_nofollow() when opening the in-tree
files. We'll continue to follow links for core.excludesFile, as well as
$GIT_DIR/info/exclude.
