Allow build of dropbear without wtmp and lastlog support to stop it from generating system log error messages

Buildroot does not have wtmp or lastlog support by default so allow dropbear to be configured to stop using them and hence to stop generating system log error messages.

It seems I had problems with git send-email sending direct to the list (the patch failed to appear within a day) so I have forwarded the copy it cc'ed to myself to the list...

Committed, thanks - I prefer positive options (E.G. to enable wtmp/lastlog logging - And I disable them by default as that's what most people would want).
