datapath,daemon: Enable multi-dev XDP

This commit enables XDP (bpf_xdp) on all devices specified by --devices.
Previously, only --direct-routing-device (or --devices if dev count = 1)
could have been used to run bpf_xdp.

To do so, we rely on the bpf_redirect() helper which performance
(>= 5.5 Linux kernel) recently became on par with bpf_redirect_map()
[1]. Therefore, it does not make sense to use the latter.

The side effect of the enablement is that the --prefilter-device no
longer makes sense. This will be addressed in a following commit.
