t: add basic tests for our SHA-1 implementation

We have in the past had some unfortunate endianness issues with some SHA-1 implementations we ship, especially on big-endian machines. Add an explicit test using the test helper to catch these issues and point them out prominently. This test can also be used as a staging ground for people testing additional algorithms to verify that their implementations are working as expected.
