ebpf_get_next_map was obsoleted by standard libbpf apis
(specifically bpf_map_get_next_id and bpf_map_get_fd_by_id)
and isn't called by anything including test code.
This increases our code coverage percentage.

* Make bpf_printk more cross-platform friendly
* Add printk_legacy.c with the define that many eBPF programs
seem to hard code.
* Updated bpf_helper_defs.h to include that exact define so
a duplicate define will not cause an error, but programs
that don't define bpf_printk can use it as they do now.
