[Patch v7 6/6] kdump.conf: renew the path section

In case no target is specified explicitly in /etc/kdump.conf, the behavior of path is changed, a check need be taken to see if any separate file system is mounted on any tier of 'path', and also to take the relevant action. Now the path section need be renewed for kdump.conf and its man page accordingly.
