Simplify custom_java_home.gradle script 

Setting `options.fork = true` causes the classpath in the forked
compiler process to include Class-Path entries from MANIFEST.MF files
in JARs in the classpath, which results in warnings about missing
classpath entries.

This commit removes the `options.fork = true` declaration and further
simplifies the script.
