Skip BinLogTest on OSX due to lock contention performance issues

[jameshilliard]

This test takes about 20 minutes to run on OSX due to OSX having very bad performance under high contention locking between multiple threads.

Test barely takes a few minutes in macOS.

I wrote this test while coding BinLog stuff, I'm OK reducing the log size (we don't need 100k entries, probably 10k is OK), but I don't think it's a good idea to just ignore the whole test.

What are the specs on your system?

I just ran this in a MacBook Pro (Retina, 15-inch, Late 2013) 2.3 GHz Intel Core i7 with SDRAM, 16GB RAM. Probably faster in my office's one, this one is old.

Think I tracked it down, I was off on the root cause, #152 should hopefully be correct.
