Updating safari_set_java_whitelist_at_login.sh and xprotect_re-enable_java_6_and_7.sh

Removing awk print $4 from safari_set_java_whitelist_at_login.sh
because I noticed it was adding an extra space at the end of the
WHITELIST_CHECK output.

Also making a logging change to the Java 6 message log in
xprotect_re-enable_java_6_and_7.sh, so that it now reports "Current
Java 6 version is ${CURRENT_JAVA_6_BUILD} and Xprotect minimum build is
${XPROTECT_JAVA_6_BUILD}, nothing to do here."

Old message was "Current JVM build is ${CURRENT_JAVA_6_BUILD} and
Xprotect minimum build is ${XPROTECT_JAVA_6_BUILD}, nothing to do here."
