skipped tests due to no `GetTotalMemory` implementation

	func GetTotalMemoryWithoutLogging() (int64, string, error) {
	totalMem, err := func() (int64, error) {
	mem := gosigar.Mem{}
	if err := mem.Get(); err != nil {
	return 0, err
	}

We don't implement this function in our patched gosigar which doesn't affect runtime (as we're using Cockroach, anyway), but we have to skip a couple of tests (skips added in f46ecb2).

Presumably the metrics recorder is what continually logs "not implemented on illumos" every 10s or so during runtime.
