P11TlsKeyMaterialGenerator should work with ChaCha20-Poly1305

TLS *_CHACHA20_POLY1305_* cipher suites are currently broken when configuration with SunPKCS11 provider is used. I discovered this by my ssl-tests testsuite [1].

make TEST_PKCS11_FIPS=1 SSLTESTS_SSL_CONFIG_FILTER=SunJSSE,Default,TLSv1.2,TLS_DHE_RSA_WITH_CHACHA20_POLY1305_SHA256 SSLTESTS_CUSTOM_JAVA_PARAMS=-Djdk.tls.ephemeralDHKeySize=2048 ssl-tests

FAILED: SunJSSE/Default: TLSv1.2 + TLS_DHE_RSA_WITH_CHACHA20_POLY1305_SHA256

Problem:
Exception is thrown by P11TlsKeyMaterialGenerator.engineGenerateKey method [2], based on result of P11SecretKeyFactory.getKeyType method [3], which only "knows" "ChaCha20" key algorithm, but does not accept "ChaCha20-Poly1305" as algorithm. Algorithm value is passed from SSLTrafficKeyDerivation.LegacyTrafficKeyDerivation class [4], which leads to algorithm field in SSLCipher class [5]. Value of that field comes from cipher name in JsseJce class [6] (ending at first slash, if any).

Fix:
This fix basically modifies P11SecretKeyFactory.getKeyType method to accept "ChaCha20-Poly1305" as alias for "ChaCha20".

Testing:
I ran jdk_security tests locally and they passed. Also failure in ssl-tests gets fixed.
