fixed tools.jar profile makes hibernate-search not buildable on Mac w/ Jdk 7

byteman is test scope dependency of hibernate-search, and due to the profile in byteman, it is always trying to fine the tools jar in _ <tools.jar>${java.home}/../Classes/classes.jar</tools.jar>_

but from JDK 7, it is Oracle, that providing JDK for Mac OS, and this Oracle JDK, there is a tools.jar, just like on other platform, and it is located in ${JDK_HOME}/lib/tools.jar

for now, it is not buildable on mac, and an error is always given like below:

"
