Previously we were relying on Gradle to substitute JDK environment variables
in toolchains.xml. With this change, the actual path to the JDK is encoded instead.
This should avoid issues where Gradle is not able to successfully resolve the
envioronment variable.
Different runners have different JDKs installed, so using a hard-coded
list for
`toolchains.xml` doesn't work. With this change, the file is generated
based on the available `JAVA_HOME_*` environment variables.
Fixes#89
