kernel_patch_verify: allow kmake to do word splitting

More issues with quoting variables that are meant to be split up on
usage.

KP_PARAMS takes multiple parameters, but gets quoted out.. and similar
issues with other variables.

Add Documentation around the same not to allow the next person to come
and quote things up.

Fixes: eeac60b kernel_patch_verify: quote damn near everything
