virnetdev: Check for defined IFLA_VF_*

The linux-2.6.32 kernel header does not yet define IFLA_VF_MAX and others,
which breaks compiling a new libvirt on old systems like Debian Squeeze.

(I also have to add --without-macvtap --disable-werror --without-virtualport to
 ./configure to get it to compile.)
