[libvirt] [PATCH v2]virsh: Add helper to avoid the strcase check for virsh-*.c

[Osier Yang]

* tools/virsh.c: New macro vshStrcasecmp
* tools/virsh-domain-monitor.c: Use vshStrcasecmp instead of
                                strcasecmp
* tools/virsh-snapshot.c: Likewise
* cfg.mk: Only avoid doing strcase checking for virsh.c
