LOG: [Binary] Hard-code the alignment of the offloading binary

Summary:
We previously used `alignof` to get the necessary alignment of the
binary header. However this was different on 32-bit platforms and caused
a few tests to fail because of it. This patch just changes this to be a
hard-coded constant of 8.
