fs-util: change chase_symlinks() behaviour in regards to escaping the root dir

Previously, we'd generate an EINVAL error if it is attempted to escape a root
directory with relative ".." symlinks. With this commit this is changed so that
".." from the root directory is a NOP, following the kernel's own behaviour
where /.. is equivalent to /.

As suggested by @keszybz.
