In certain cases crypto code needs to zeroize their local hmac_sha1_key or hmac_sha1_ctx structures after use to avoid leaking sensitive material. Provide hmac_sha1_zeroize_key() and hmac_sha1_zeroize_ctx() helper functions that e.g. can be used with __cleanup() to automatically zeroize the structures when they go out of scope. While we're at it, replace the related memzero_explicit() call in lib/crypto/sha1.c with a call to the new helper function.
