resolv.conf nameserver line has only one entry, ignore trailing garbage
**What this PR does / why we need it**:
Per the resolv.conf man page "name servers may be listed, one per keyword." Some tools such as udhcpc take advantage of this to append comments to nameserver entries. For example: `nameserver 8.8.8.8 # eth0`. This updates the resolv.conf parser to ignore trailing garbage on nameserver lines.
**Release note**:
NONE
