tests: fix bpf-obj_get_info_by_fd-prog-v expected output

Since we cannot reliably predict the value of xlated_prog_len field
returned by the kernel, do not hard-code it.

* tests/bpf-obj_get_info_by_fd.c (main): Print the value
of the xlated_prog_len field returned by the kernel
instead of hard-coding an expected value.

Fixes: v5.14-46-g835c65c0e "bpf: fix bpf_prog_info.map_ids array printing"
