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.
