ARM: 9473/1: kprobes: test: add MODULE_DESCRIPTION

All loadable modules must have a description, and since commit
6c6c1fc09d ("modpost: require a MODULE_DESCRIPTION()"), the kernel build
warns about it missing:

   WARNING: modpost: missing MODULE_DESCRIPTION() in arch/arm/probes/kprobes/test-kprobes.o

Add the missing description tags. Noticing that the existing license tag
is unnecessarily hidden in an #ifdef section, remove the #ifdef and
use conventional placing of the initcall and module_exit tags as well
as the license and description.
