RFR: 8372247: OSX: Semaphore.trywait requires os::Bsd::clock_init [v2]

[Axel Boldt-Christmas]

> The OSX implementation of the Semaphore requires `os::javaTimeNanos` which requires that we have initiated the clocks via `os::Bsd::clock_init()`. Or we will get an integer division by zero when performing a trywait.
> 
> I propose that we let this test setup `os::Bsd::clock_init()` rather than being forced to run in VM.
> 
> An alternative would be to simply run this test in VM. Making the dependency more clear. Or only use VM for `__APPLE__`.
