  speed: Fix memory leak

Free the signature stack after iterating over all found signatures.
Free the kem and signature stacks at the end of speed_main() if not
NULL.

  speed: Fix execution of EdDSA measurement

Running 'openssl speed eddsa' fails with

Doing 253 bits sign Ed25519 ops for 10s: EdDSA sign failure
000003FF9306C7D0:error:030000BC:digital envelope routines:EVP_DigestSign:
                           final error:crypto/evp/m_sigver.c:585:
-1 253 bits Ed25519 sign ops in 0.00s
Doing 253 bits verify Ed25519 ops for 10s: EdDSA verify failure
000003FF9306C7D0:error:030000BC:digital envelope routines:EVP_DigestVerify:
                           final error:crypto/evp/m_sigver.c:694:
-1 253 bits Ed25519 verify ops in 0.00s

This is because the EVP_DigestSign/Verify() calls in the EdDSA_sign/verify_loop()
fail because the context has already been finalized by the previous
EVP_DigestSign/Verify call during the EdDSA signature test done by speed_main().

This happens since commit 3fc2b7d6b8f961144905330dfd4689f5bd515199 where the
EVP_DigestSign/Verify() functions have been changed to set a flag that the
context has been finalized.

Fix this by re-initializing the context using EVP_DigestSign/Verify() in the
EdDSA_sign/verify_loop().
