Commit cfc1d277891e ("module: Move all into module/") changed the prefix
of the module param by moving/renaming files. A later commit also moves
the module_param() into a different file, thereby changing the prefix
yet again.
This would break kernel cmdline compatibility and also userspace
compatibility at /sys/module/module/parameters/sig_enforce.
So, set the prefix back to "module.".
