Update VMP/RA Tests

Before the VMP/RA tests only tested that decryption was successful
(checking the return code) but did not test the actual success of the
decryption (checking the decrypted plaintext against golden
plaintext).

This brings this repo in sync with the internal repo's commit
58d85cf6b19ecfb932f8edc2eaa8e907a1d21489.
