kdump.conf: renew the path section

Browse Source 
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.
