selftests/bpf: test_xsk: Integrate test_xsk.c to test_progs framework

Browse Source 
test_xsk.c isn't part of the test_progs framework.

Integrate the tests defined by test_xsk.c into the test_progs framework
through a new file : prog_tests/xsk.c. ZeroCopy mode isn't tested in it
as veth peers don't support it.

Move test_xsk{.c/.h} to prog_tests/.

Add the find_bit library to test_progs sources in the Makefile as it is
is used by test_xsk.c
