Add GODEBUG option to use legacy filepath.EvalSymlinks()

In go 1.23 filepath.EvalSymlink(path) behavior has changed
and it returns an error if path is a Windows junction. The
new behavior breaks some functionalities (see containers#24557).

The GODEBUG option `winsymlink=0` allow to get run `EvalSymlink`
with its legacy behavior.
