libpayload: Add comments on virtual pointers in lib_sysinfo

After another incident related to virtual pointers in lib_sysinfo (and
    resulting confusion), I decided to put some comments on the matter into
    the code.

Remember, we decided to always use virtual pointers in lib_sysinfo, but
    it's not always obvious from the code, that they are.
