rmodules: use rmodtool to create rmodules

Start using the rmodtool for generating rmodules.
    rmodule_link() has been changed to create 2 rules:
    one for the passed in <name>, the other for creating
    <name>.rmod which is an ELF file in the format of
    an rmodule.

Since the header is not compiled and linked together
    with an rmodule there needs to be a way of marking
    which symbol is the entry point. __rmodule_entry is
    the symbol used for knowing the entry point. There
    was a little churn in SMM modules to ensure an
    rmodule entry point symbol takes a single argument.
