tests: More robust parsing of resolv.conf for DHCP tests
To check publishing of DNS information via DHCP, we need to extract a list of nameservers and/or search domains from resolv.conf in the test script. The current version (usually) leaves the result with a trailing ','. That's usually ok because it happens on both guest and host sides. However it's kind of confusing, and might stop working if the host had a resolv.conf without a trailing \n on the last line. It also makes some later changes we'll need more difficult. So, normalize the output from resolv.conf a bit further, removing any trailing ','. It turns out we can do this with a slightly less complex sed expression than the one we already have.
