perf/hw_breakpoint: test: Skip the test if dependencies unmet
Running the test currently fails on non-SMP systems, despite being
enabled by default. This means that running the test with:
./tools/testing/kunit/kunit.py run --arch x86_64 hw_breakpoint
results in every hw_breakpoint test failing with:
# test_one_cpu: failed to initialize: -22
not ok 1 - test_one_cpu
Instead, use kunit_skip(), which will mark the test as skipped, and give
a more comprehensible message:
ok 1 - test_one_cpu # SKIP not enough cpus
This makes it more obvious that the test is not suited to the test
environment, and so wasn't run, rather than having run and failed.
