Backport #8805: Ruby GC::Profiler returns incorrect info on Solaris (and relatives)

We use SmartOS as our deployment platform, and noticed when attempting to roll out Ruby 2.0.0-p247 to some SmartOS hosts that garbage collection info is broken with integrations such as New Relic. Investigating further, we found that GC::Profiler.total_time always returns 0.0.

>> GC::Profiler.enable
=> nil
>> GC.start
=> nil
>> GC::Profiler.total_time
=> 0.0

It may be related to this issue: https://bugs.ruby-lang.org/issues/7500 where the mechanism by which the profiler gets timestamps from the OS.
