Upgrade KeyMint version

This is a cherry-pick of a change to internal master to upgrade the
KeyMint version.

The cherry-pick is necessary because the changes to support Curve
25519 will land in AOSP and there are currently merge conflicts for
Android.bp with internal master.

Bug: 194359292
Test: That it compiles.
