KVM: selftests: fix vmx_preemption_timer_test build with GCC10

GCC10 fails to build vmx_preemption_timer_test:

gcc -Wall -Wstrict-prototypes -Wuninitialized -O2 -g -std=gnu99
-fno-stack-protector -fno-PIE -I../../../../tools/include
 -I../../../../tools/arch/x86/include -I../../../../usr/include/
 -Iinclude -Ix86_64 -Iinclude/x86_64 -I..  -pthread  -no-pie

 ./linux/tools/testing/selftests/kselftest.h
 ./linux/tools/testing/selftests/kvm/libkvm.a
 -o ./linux/tools/testing/selftests/kvm/x86_64/evmcs_test

 ...

ctrl_exit_rev/ctrl_pin_rev/basic variables are only used in
vmx_preemption_timer_test.c, just move them there.
