Ihor Solodrai cb4a119252 scripts/bpf_doc.py: implement json output format ...

bpf_doc.py parses bpf.h header to collect information about various
API elements (such as BPF helpers) and then dump them in one of the
supported formats: rst docs and a C header.

It's useful for external tools to be able to consume this information
in an easy-to-parse format such as JSON. Implement JSON printers and
add --json command line argument.

v3->v4: refactor attrs to only be a helper's field
v2->v3: nit cleanup
v1->v2: add json printer for syscall target
