Latency testing: request even number of CPUs for latency pods

Due to modification done in #830, tests requesting odd number of CPU are failing due to rejecting the pod from running with SMTAlignmentError.

Adjust the tests to use an even number of CPUs.
Configuring a relevant PP for the tests use will follow in a separate patch.
