Since commit 834c5720 which extracted the generic functionality out of virsh and made it available for other clients like virt-admin to make use of it, it also introduced a bug when it renamed the original VIRSH_ environment variables to VSH_ variables. Virt-admin of course suffers from the same bug, so this patch modifies the generic module vsh.c to construct the correct name for environment variables of each client from information it has.
