selftests/bpf: add test for bpf_msg_pop_data() overflow
Add a test in sockmap_basic.c that calls bpf_msg_pop_data() with a length
close to U32_MAX, which overflows the start + len bounds check. The sk_msg
program records the return value over a sendmsg and the test checks that
the call is rejected with -EINVAL.
