lnwallet: Implement test vectors from BOLT 03, Appendix C.

Browse Source 
Appendix C of BOLT 03 contains a series of test vectors asserting that
commitment, HTLC success, and HTLC timeout transactions are created
correctly. Here the test cases are transcribed to Go structs and
verified.

We also break out some logic need to tests that bypass the constructor
and remove some redundant fields.
