brew fc test fix for packed_fc
brew fc test fix for packed_fc

Summary:
It turned out that we can not run PackedFC on a machine that does not have avx2 right now, as there is an known issue with MKL 2017.0.098 that produces wrong results on non-avx2 machines.
I just moved this test from here because this is not the purpose of this test
