Well, that was unexpected

It seemed the old setup-java version installed a JDK for x64?
And it worked? But causes the linking step to complain a bunch
of PostgreSQL symbols can't be found ... for x86_64?

This should correctly find the mixed-case JAVA_HOME_* variables.

Also using newer versions of setup-java and checkout actions.
