Fix support for :boot-jvm-options

[jeroenvandijk]

This patch fixes the use of the :jvm-options property (via one of the config options) as documented in the WIKI

Testing

Add BOOT_JVM_OPTIONS=-XX:-OmitStackTraceInFastThrow to your boot.properties file

Now start a boot repl and run this command:

(let [x (fn [] (/ nil 1)) cnt0 20000] (loop [cnt 0] (when-not (= cnt cnt0) (recur (try (x) (catch Exception e (print ".") (flush) (if (seq (.getStackTrace e)) (inc cnt) (do (println "No stacktrace at" cnt) cnt0))))))))

It will say "No stacktrace at ***", where the number is probably smaller than 10000.

Now compile boot again from this branch:

 make bin/boot.sh backup-boot-bin install-boot-bin

And the above steps will not give "No stacktrace at ***"

The old boot script can be reverted via

make restore-boot-bin
