* gnu/pcakages/java.scm: Add -XX:+UseParallelGC to generated wrapper scripts
for TLA+'s binary tools.

TLA+'s tools request (and throw a warning message) when you invoke them
without Java's parallel GC flag. Including this flag removes the warning
message and should improve performance (theoretically).
