This set aims at improving the checks for building bpftool's documentation
(including the man page for eBPF helper functions). The first patch lowers
the log-level from rst2man and fix the reported informational messages. The
second one extends the script used to build bpftool in the eBPF selftests,
so that we also check a documentation build.

This is after a suggestion from Andrii Nakryiko.

  tools: bpftool: log info-level messages when building bpftool man
    pages
  selftests, bpftool: add bpftool (and eBPF helpers) documentation build

I see, indeed with this patch we would only build the doc on "make
run_tests", not when building the selftests. I'll send another version
that builds the doc at the same time as we build bpftool then.

I also had another look at rst2man's options, and there's probably
cleaner a way to get rid of the stderr redirection/line counting that
I'm doing in this version. I'll fix that too.

Thanks for the feedback.
