module: taint kernel when lve module is loaded

commit c99af3752bb52ba3aece5315279a57a477edfaf1 upstream.

Cloudlinux have a product called lve that includes a kernel module. This
was previously GPLed but is now under a proprietary license, but the
module continues to declare MODULE_LICENSE("GPL") and makes use of some
EXPORT_SYMBOL_GPL symbols. Forcibly taint it in order to avoid this.
