TODO(pldd): cheri: elf: fix pldd to compile for purecap abi

Adjust types in the E(*) structs to support capabilities.

TODO: purecap pldd should refuse to deal with lp64 and ELF32 processes.
the code for the 32bit case should be disabled.
TODO: a correct fix requires support for all abis that can run on the
same system (purecap, lp64 and ELF32 too).
