kexec-tools: Refine kdump device_tree sort
The commit b02d735bf was to rearrange the device-tree entries, and
assumed that these entries are sorted in the ascending order. but
acctually when I was validating kexec and kdump, the order of
serial node still is changed. So the patch is to sort these entries
by the directory name in ascending order.
