[PATCH 3/9] build: eliminate useless WITH_VIRTUALPORT check

WITH_VIRTUALPORT just checks that we are building on Linux and that IFLA_PORT_MAX is defined in linux/if_link.h. Back when 802.11Qb[gh] support was added, the IFLA_* stuff was new (introduced in kernel 2.6.35, backported to RHEL6 2.6.32 kernel at some point), and so this extra check was necessary, because libvirt was being built on Linux distros that didn't yet have IFLA_* (e.g. older RHEL6, all RHEL5). It's been in the kernel for a *very* long time now, so all supported versions of all Linux platforms libvirt builds on have it. Note that the above paragraph implies that the conditional compilation should be changed to #if defined(__linux__). However, the astute reader will notice that the code in question is sending and receiving netlink messages, so it really should be conditional on WITH_LIBNL (which implies __linux__) instead, so that's what this patch does.
