KVM: selftests: Move raw KVM_SET_USER_MEMORY_REGION helper to utils
Move set_memory_region_test's KVM_SET_USER_MEMORY_REGION helper to KVM's
utils so that it can be used by other tests. Provide a raw version as
well as an assert-success version to reduce the amount of boilerplate
code need for basic usage.
No functional change intended.
