Jeremie Koenig b175462422 readlink: use xmalloc_realpath() 
Using realpath() directly with a non-NULL output buffer is unsafe because its
behavior is unspecified on systems which don't have PATH_MAX (ie. Hurd)

I beleive this also fixes a small bug whereby 'buf' would not be freed
on 'readlink -v' with ENABLE_FEATURE_CLEANUP.
