Subject: [PATCH 15/26] lib/crypto: tests: Add KUnit tests for SHA-1 and HMAC-SHA1

From: Eric Biggers <[email-masked]>
Date: Sat, 12 Jul 2025 16:23:06 -0700

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.
