Improvements to tombstone output.

- Use "likelihood" instead of "probability" since that has connotations
  of being less precise, and our probability ordering isn't very precise
  anyway.

- Hide the fault address with SEGV_MTEAERR because it is not available.

- Pad the fault address with leading zeroes to make it clearer which
  bits of the top byte (and any following bytes such as PAC signature
  bits) are set.
