Daniel P. Berrangé 1f37280b37 net: fix build when libbpf is disabled, but libxdp is enabled 
The net/af-xdp.c code is enabled when the libxdp library is present,
however, it also has direct API calls to bpf_xdp_query_id &
bpf_xdp_detach which are provided by the libbpf library.

As a result if building with --disable-libbpf, but libxdp gets
auto-detected, we'll fail to link QEMU

  /usr/bin/ld: libcommon.a.p/net_af-xdp.c.o: undefined reference to symbol 'bpf_xdp_query_id@@LIBBPF_0.7.0'

There are two bugs here

 * Since we have direct libbpf API calls, when building
   net/af-xdp.c, we must tell meson that libbpf is a
   dependancy, so that we directly link to it, rather
   than relying on indirect linkage.

 * When must skip probing for libxdp at all, when libbpf
   is not found, raising an error if --enable-libxdp was
   given explicitly.
