CLOUDSTACK-9042: VR: DHCP: fix missing DHCP host enties

in /etc/dhcpentries.txt we had:

02:00:1e:07:01:53,set:10_102_92_5,10.102.92.5,songlog-1,infinite
02:00:0b:a2:00:3d,set:10_102_92_234,10.102.92.234,log-1,infinite

This sed matched unexpectetly "songlog-1" as well when "log-1" was processed, resulting
missing dhcp entry for songlog-1.

Also fixed other potenials problems relating to sed matching.

> VR advanced networking.
> We experienced an issue when a few VMs were started at a time, some of them and always
the same ones did not receive a IP from DHCP. 
> After a debuging, we identified the problem in this sed command in 
> ./systemvm/patches/debian/config/opt/cloud/bin/edithosts.sh
> the VM which was not in /etc/dhcphosts.txt was named:
> songlog-1
> When another VM was started named "log-1" the "songlog-1" entry was removed unexpectedly.
