Keep staging on the cache filesystem.

Robolectric stages the JAR in /tmp, then copies it across this mount. If the container stops during that copy, the persistent cache can contain a partial JAR. Later runs accept the existing file without validating it and continue to fail. (raw.githubusercontent.com)

Set the test JVM’s java.io.tmpdir to a directory inside /root/.m2, so installation can use an atomic rename.

Review comment at @scripts/remote-gradle.sh at line 74:
Set the test JVM’s java.io.tmpdir to a directory within the mounted /root/.m2
cache in the remote Gradle setup, so staged artifacts can be installed with an
atomic rename on the same filesystem.
