[PATCH] libvirtd: diagnose explicitly requested but missing conf file

[Eric Blake <eblake@xxxxxxxxxx>]

Fixes test regression introduced in commit 8e2e4780.

* daemon/libvirtd.c (daemonConfigLoad): Add argument.
(main): Update caller.
---

Pushing under the build-breaker rule, since it is detected by 'make check'.
