build: uprev dependencies and fix script block order

- buildscript must always be the first block in a Gradle build

- ConstraintLayout, Kotlin and bintray plugin are updated to their latest stable revisions

- Biometrics is updated to the latest alpha release to make use of multiple memory leak fixes that plague the 1.0.x implementations
