Revert "Print full diagnostics file when Java process crashes."

This reverts commit 09fd82ea.

Reason for revert: This change set the value of JAVA make variable to a string containing "foo bar". When soong_ui is asked to evaluate such string, it drops the quotes, causing bash to treat 'foo' and 'bar' as separate command line arguments.
