[libvirt] [PATCH] virGet{User, Group}Ent() don't say success on fail

[Doug Goldstein]

When virGetUserEnt() and virGetGroupEnt() fail due to the uid or gid not
existing on the machine they'll print a message like:

$ virsh -c vbox:///session list
error: failed to connect to the hypervisor
error: Failed to find user record for uid '32655': Success

The success at the end is a bit confusing. This changes it to:

$ virsh -c vbox:///session list
error: failed to connect to the hypervisor
error: Failed to find user record for uid '32655'
