If you're running OS X 10.11 (El Capitan), there is a new feature called "Rootless" which prevents editing of files under /System/ except by installers and the like. You may be able to solve whatever problem is requiring you to update the CurrentJDK symlink just by setting the JAVA_HOME environment variable to /Library/Java/JavaVirtualMachines/jdk1.7.0_79.jdk/Contents/Home

If you truly want to modify that /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK symlink, you will likely have have to disable Rootless mode. You could also try running the Java 7 installer again, though I'm not certain that this will work
