[PATCH] module support: record in vermagic ability to unload a module

An UML user reported (against 2.6.13.3/UML) he got kernel Oopses when
trying to rmmod (on a kernel with module unloading enabled) a module
compiled with module unloading disabled.  As crashing is a very correct
thing to do in that case, a solution is altering the vermagic string to
include this too.

Possibly, however, the code should not crash in this case, even if the
module didn't support unloading - it should simply abort the module
removal.  In this case, fixing that bug would be a better solution.  I've
not investigated though.

(akpm: a bit marginal - root screwed up and shot himself in the foot).
