ARM: Thumb-2: Reflect ARM/Thumb-2 configuration in module vermagic
Loading Thumb-2 modules into an ARM kernel or vice-versa isn't
guaranteed to work safely, since the kernel is not interworking-
aware everywhere.
This patch adds "thumb2" to the module vermagic when
CONFIG_THUMB2_KERNEL is enabled, to help avoid accidental loading
of modules into the wrong kernel.
