redhat: disable kunit by default
KUNIT has some slight overhead even when not being run. Upstream has
made some strides on removing and isolating this overhead. One of these
ways is completely disable kunit and only enabling it at boot time via
a cmdline arg kunit.enable=1.

redhat: fix kunit compiling error
The cpumask_kunit.ko file is still being included in the kernel build
