selftests/bpf: Migrate test_xdp_redirect.c to test_xdp_do_redirect.c

prog_tests/xdp_do_redirect.c is the only user of the BPF programs
located in progs/test_xdp_do_redirect.c and progs/test_xdp_redirect.c.
There is no need to keep both files with such close names.

Move test_xdp_redirect.c contents to test_xdp_do_redirect.c and remove
progs/test_xdp_redirect.c
