Add a check for history section location to find-doc-nits

Check that the HISTORY section is located after the SEE ALSO section,
this is a much more frequent order in OpenSSL manual pages (and UNIX
manual pages in general).

Also check that SEE ALSO comes after EXAMPLES, so that the tool can
ensure the correct manual section sequence.
