    gnu: openjdk: Fix library substitution when libraries aren't found.
    
    * gnu/packages/java.scm (icedtea-8, openjdk9, openjdk11)[arguments]:
    Change 'find-library' to always return a string.  Change 'find-library'
    callers to use 'string-append' rather than 'format'.  Starting from
    97a43db8b4416a1450aa61737edba9cf4126cf1c, 'find-library' could return #f
    and JNI substitutions would emit a literal "#f".
