bug#42423: icedtea: JAVA_HOME

[Christopher Howard]

Hi, I'm not going to pretend to be a Java expert, but I was trying to
build and run a Java application, and had to set JAVA_HOME manually. It
is my understanding from my research[1] that applications often will
want JAVA_HOME set to the path to the java install directory. It would
seem like it would be useful if Guix set that as well for the icedtea
and icedtea:jdk package.

If there are good reasons for that not to be, perhaps more
knowledgeable individuals will explain it.

One part I'm not quite sure about is what JAVA_HOME would be set to if
both icedtea and icedtea:jdk were installed.
