Relax the thread count assertion, that is modify EXPECT_EQ -> EXPECT_GE (#79806)

Summary:
D36484910 added logarithm integration which ended up starting a new thread with the following stacktrace and causing the [caffe2/caffe2:caffe2_test_cpu_asan_no_sig tests](https://fburl.com/test/jk58c0el) to fail:
