smilatency test is latency sensitive and does not pass deterministically when
run in QEMU environment under biosbits. Disable the test suite for now.

Example failure:

==== SMI latency test ====
Warning: touching the keyboard can affect the results of this test.
Starting test. Wait here, I will be back in 15 seconds.
[assert] SMI latency < 150us to minimize risk of OS timeouts FAIL
  1us   < t <=  10us; average = 1372ns; count = 10912449
   Times between first few observations:  176us 1646ns 1441ns 1450ns 1462ns
  10us  < t <= 100us; average = 16us; count = 1187
   Times between first few observations:   15ms 3148us 5856us   49ms   33ms
  100us < t <=   1ms; average = 259us; count = 8
   Times between first few observations:  111ms 2227ms 1779ms  999ms  219ms
  0 SMI detected using MSR_SMI_COUNT (MSR 0x34)
  Summary of impact: observed maximum latency = 298us
Summary: 0 passed, 1 failed
