Fixed ifup error on Debian

When running /sbin/ifup vmbr1, the following error appears:
 Usage: vzarp-ifup DEVICE
 run-parts: /etc/network/if-up.d/vzifup-post exited with return code 1

According to Debian's interfaces(5), the interface name is passed to
post-up scripts via the $IFACE environment variable, not via a
command-line argument as in SuSE.
