tests: Move MI_Example tests to Long/Nightly

Two tests, one in test_kvm_fork_run.py and another in
test_kvm_cpu_switch.py, were trying to run the MI_Example protocol as
part of the quick/kokoro run. MI_Example requires the building of X86,
though we try to use GCN3_X86 exclusively to avoid compiling an
additional target. As such, these MI_Example tests have been moved to
the long/nightly run.
