[libvirt] [PATCH libvirt-snmp 3/3] fix startup logic for selecting stderr vs syslog

[Laine Stump]

This bug was uncovered by coverity during the run that resulted in the
filing of the following bug:

   https://bugzilla.redhat.com/show_bug.cgi?id=732015

use_syslog was initialized to 0, and then if the "Use stderr" option
was selected, it was set to ... "0"!

Rather than simply initializing to 1, I decided to reduce confusion by
renaming the variable to "use_stderr", leave it initialized to 0, then
set to 1 when the user asks for stderr.
