parser: don't abort profile compile if the kernel is missing caps/mask

3.0 added the ability to extract and use the kernels cap mask to augment its internal capability list as a stop gap measure to support new capabilities.

Unfortunately not all kernel export the cap/mask and this is causing the policy compile to fail. If the kernel doesn't export a cp/mask just use the internal list.
