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.
