    fixup! Bug #4234: Use the Firefox Update Process for Tor Browser.
    
    Modify the AddSymlink implementation to use absolute paths when creating
    symlinks. This fixes a compile error that was introduced due to the changes
    Mozilla made for https://bugzilla.mozilla.org/show_bug.cgi?id=1246972.
