virsh: don't override connection URI from argv
Currently, if a connection URI was specified on the command line by the '-c' switch, virsh connects to it, but after connecting overrides its value with the one it tries to obtain from the VIRSH_DEFAULT_CONNECT_URI environment variable. This makes virsh connecting to the wrong URI if it disconnects from the hypervisor and then tries to reconnect, and also leaks the original connname. Fix by calling virGetEnvBlockSUID() before virshParseArgv().

LibVirt : simple API for virtualization Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). It is free software available under the GNU Lesser General Public License. Virtualization of the Linux Operating System means the ability to run multiple instances of Operating Systems concurrently on a single hardware system where the basic resources are driven by a Linux instance. The library aim at providing long term stable C API initially for the Xen paravirtualization but should be able to integrate other virtualization mechanisms if needed. Daniel Veillard <veillard@redhat.com>
Description
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
