Package 0.6.0 release for Ruby (#59)

I'm following the instructions in <ruby/README.md> on how to package
newer versions of libddprof for release.

I haven't actually been pushing every release to rubygems.org, since
the PR on the Ruby side that will pull it in is still unmerged
(<DataDog/dd-trace-rb#1936>) and thus there's
no need to litter up the releases list.

Nevertheless, I like being ready to release, so I decided to bump this
version anyway.
