app-admin/logstash-bin: version bump to 2.3.2

Package-Manager: portage-2.2.28

I have had a look at this ebuild and have a couple of minor notes for future reference:

• EAPI could be bumped to EAPI6
• IUSE does not need to be defined if there are no flags
• DEPEND does not need to be defined if there are no build-time dependencies

Otherwise, this is good - my testing was all successful - and once the QA check comes back I will push.

Thanks!

Thanks @wraeth, I'll incorporate the changes into the next bump :)
