qemu: disbale AF_XDP network backend support

This fix some host contaminations issues:
| /poky/build/tmp/hosttools/ld.bfd: libcommon.fa.p/net_af-xdp.c.o: undefined reference to symbol 'bpf_xdp_detach@@LIBBPF_0.7.0'
| /poky/build/tmp/hosttools/ld.bfd: /usr/lib/libbpf.so.1: error adding symbols: DSO missing from command line
| collect2: error: ld returned 1 exit status

The AF_XDP network backend support [1] requires the libxdp that is not
available in any layer, otherwise you can configure this option:
| PACKAGECONFIG[af-xdp] = "--enable-af-xdp,--disable-af-xdp,libxdp"
