Fix reporting of the CloudABI ABI in kdump.
- Advertise the word size for CloudABI ABIs via the SV_LP64 flag. All of the other ABIs include either SV_ILP32 or SV_LP64. - Fix kdump to not assume a 32-bit ABI if the ABI flags field is non-zero but SV_LP64 isn't set. Instead, only assume a 32-bit ABI if SV_ILP32 is set and fallback to the unknown value of "00" if neither SV_LP64 nor SV_ILP32 is set.
