Small patch

Description of problem:

Kdump which is configured to copy vmcore on the remote server via SSH doesn't set  network up if it has a bond interface with slave that has "-" symbol in its name. Mkdumprd copies network scripts (from /etc/sysconfig/network-scripts/) into $MNTDIR/etc directory with theirs original names. Then it uses script's name to get device's name in this way:

for i in `ls /etc/ifcfg-*`
do
   NETDEV=`echo $i | cut -d"-" -f2`
   map_interface $NETDEV
done

I have an interface named "gige-11-1". So I will get "gige", insdead of "gige-11-1" and network will not work (kdump will not be able to copy vmcore on the remote server). 

Version-Release number of selected component (if applicable):
kexec-tools-2.0.0-209.el6_2.5.x86_64 (RHEL 6.2)

How reproducible:
100%

Steps to Reproduce:
1. Make bond interface with 2 slaves ("gige-11-0" and "gige-11-1")
2. Configure kdump to copy vmcore via ssh on the remote host.
3. echo "c" > /proc/sysrq-trigger
  
Actual results:

Remote host is unreachable. Network doesn't work properly.

Expected results:

Vmcore has been copied.
