taint/module: Fix problems when out-of-kernel driver defines true or false
Commit 7fd8329ba502 ("taint/module: Clean up global and module taint
flags handling") used the key words true and false as character members
of a new struct. These names cause problems when out-of-kernel modules
such as VirtualBox include their own definitions of true and false.
