[CFI] Fix cfi-icall failures

Control Flow Integrity [1] indirect call checking verifies that function
pointers only call valid functions with a matching type signature.
webrtc casts the function pointers for external_hmac causing a cfi-icall
failure when they are later called in libsrtp. Refactor the functions to
match the correct type signatures to avoid this failure.
