Keystore 2.0: Add CREATION_DATETIME only for Keymint V1 and higher.

Adding CREATION_DATETIME unconditionally should be accepted by all
keymaster implementations. Alas, VTS tests never covered this before
Keymint V1 and so there are implementations that fail when the caller
presents the tag.

Test: CtsKeystoreTestCases for regression testing.
