test: allow more than one control cpu
test: allow more than one control cpu

A second issue was discovered in the validation test code after fixing
bug 2027 and creating default cpumasks containing all installed CPUs.

See Linaro BUG 2027 for details.
	https://bugs.linaro.org/show_bug.cgi?id=2027

The cpumask validation test expected exactly one control CPU and
returned an error otherwise.
This change considers one or more control CPUs to be correct.
