Kernel: Remove unused Thread::Blocker::should_block() virtual

Browse source 
This was previously used after construction to check for early unblock
conditions that couldn't be communicated from the constructor.

Now that we've moved early unblock checks from the constructor into
setup_blocker(), we don't need should_block() anymore.
