If we're going to do this, then we should probably also update the pt
dumping code (mm/dump.c) to avoid dumping the modules area too.

There are also some weird consequences of defining MODULES_VSIZE to be 0,
since we'll end up registering a zero-length region with KASAN and
calculating a bogus module_alloc_base in the kaslr code. This might all be
harmless, but it feels like we're laying down some tripwires for ourselves
that I'd rather avoid doing.
