kbuild: generate modules.builtin
To make it easier for module-init-tools and scripts like mkinitrd to distinguish builtin and missing modules, install a modules.builtin file listing all builtin modules. This is done by generating an additional config file (tristate.conf) with tristate options set to uppercase 'Y' or 'M'. If we source that config file, the builtin modules appear in obj-Y.
