[libvirt] [PATCH] build: remove dead variables

[Eric Blake]

Detected by Coverity.  No real harm in leaving these, but fixing
them cuts down on the noise for future analysis.

* src/rpc/virnetserver.c (virNetServerAddService): Delete unused
entry.
* src/util/sysinfo.c (virSysinfoRead): Delete dead assignment to
base.
