module.bbclass: Allow for modules to be packaged seperate from ${PN}

This patch will allow recipes that provide kernel modules to package
the module or modules in specific packages. That list is contained in
MODULE_PACKAGES, this defaults to  to preserve the current behavior.
The package can also define MODULE_FILES to specify files.
