lib/crypto: tests: Add KUnit tests for MD5 and HMAC-MD5
Add a KUnit test suite for the MD5 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.
