discover/network: Fix incorrect static DNS servers in resolv.conf
We currently have a bug where we write NUL characters into
/etc/resolv.conf, when using static DNS server configurations:
With a network setting of: dns,9.0.6.11,9.0.7.1
We generate a resolv.conf containing:
nameserver 9.0.6.11^@nameserver 9.0.7.1^@
This is due to an off-by-one bug when terminating the nameserver
entries.
