rmodule: add 16 bytes of padding

There is a plan to utlize rmodules for loading ramstage as a
    relocatable module. However, the rmodule header may change.
    In order to provide some wiggle room for changing the contents
    of the rmodule header add some padding. This won't stop the need
    for coordinating properly between the romstage loader that may be
    in readonly flash and rmodule header fields.  But it will provide
    for a way to make certain assumptions about alignment of the
    rmodule's program when the rmodule is compressed in the flash.
