creating a VM with a NIC with multicast mac (see [1]) is possible, but setting
the interface's link up inside the guest fails (tested on Debian stable).
The issue was noted with LXC first (see [0,2]) and then tested with Qemu.
This patch uses the 'mac-addr' standard_option defined in PVE::JSONSchema to
ensure only unicast MAC addresses are used for netconfig.
