[13] RFR JDK-8213008 "Cipher with UNWRAP_MODE should support the generation of an AES key type"

[Valerie Peng]

Anyone has time to help review this fix? According to the bug report, 
some vendors require the keytype attribute to match the encryption 
algorithm. So, the change is to match the key type based on the 
algorithm specified. There is no regression test as this issue is not 
reproducible against Solaris or NSS PKCS11 libraries.
