bpftool: Replace "__fallthrough" by a comment to address merge conflict
The recent support for inline annotations in control flow graphs
generated by bpftool introduced the usage of the "__fallthrough" macro
in a switch/case block in btf_dumper.c. This change went through the
bpf-next tree, but resulted in a merge conflict in linux-next, because
this macro has been renamed "fallthrough" (no underscores) in the
meantime.
To address the conflict, we temporarily switch to a simple comment
instead of a macro.
