Strip inline comments from the kdump config file before use

Browse Source 
From: Wade Mealing <wmealing@redhat.com>

The RHEL 5 release of mkdumprd allowed for comments in the kdump config
file as shown below:

net 192.168.1.1 # this is the comment part

This patch strips them out during processing, but leaves the configuration
file in original condition.
