Build with the "org.embulk.embulk-plugins" Gradle plugin

Along with that,
* Upgrade the Gradle wrapper to use Gradle 6.1.1
* Upgrade the Bintray Gradle plugin to 1.8.4 (latest)
* Upgrade depending embulk-core to 0.9.23 (latest)
* Set JavaCompile option for deprecation and unchecked
* Test with GitHub Actions, instead of Travis-CI
