module: turn longs into ints for module sizes
This shrinks module.o and each *.ko file.
And finally, structure members which hold length of module
code (four such members there) and count of symbols
are converted from longs to ints.
We cannot possibly have a module where 32 bits won't
be enough to hold such counts.
For one, module loading checks module size for sanity
before loading, so such insanely big module will fail
that test first.
