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.
