bls: debugging utils and fake sig fix
There was a discrepancy between the is_empty fields of fake signatures during testing, so I've added
a small hack to set the is_empty field of a fake signature based on the byte content.
Alternatively, we could just make it so that any fake signature is defined to be equal to any other.

Adding a #[signed_root(skip_hashing)] macro
Lets the user annotate fields of a struct to skip for signed root
hashing.

Also added tests in a `eth2/utils/tests` crate, so that we can test
whether these derived macros work as intended.
