selftests, xsk: Rename AF_XDP testing app

Recently, xsk part of libbpf was moved to selftests/bpf directory and
lives on its own because there is an AF_XDP testing application that
needs it called xdpxceiver. That name makes it a bit hard to indicate
who maintains it as there are other XDP samples in there, whereas this
one is strictly about AF_XDP.

Do s/xdpxceiver/xskxceiver so that it will be easier to figure out who
maintains it. A follow-up patch will correct MAINTAINERS file.
