rename SEC() to SECTION()

The only purpose of this is to break cut-and-paste of examples
that use SEC() causing people to think things through, look
at Android bpf program examples and use a better macro.

In particular programs with SEC("license") / SEC("maps") need to be
changed to use LICENSE("license") and the map helpers or the map
section is wrong and cannot be correctly parsed by the bpfloader.

Generated via:
  git grep 'SEC\(' | cut -d: -f1-2 | while read i; do mcedit $i; done
and manually editting found locations
