lib/crypto: tests: Add KUnit tests for SHA-1 and HMAC-SHA1
Add a KUnit test suite for the SHA-1 library functions, including the corresponding HMAC support. The core test logic is in the previously-added hash-test-template.h. This commit just adds the actual KUnit suite, and it adds the generated test vectors to the tree so that gen-hash-testvecs.py won't have to be run at build time.
