PEL: Add PEL D-Bus methods

Implement the org.open_power.Logging.PEL D-Bus interface on
/xyz/openbmc_project/logging.

It provides the following methods:
* getPEL - Return a unix FD to the PEL data based on the PEL id.
* getPELFromOBMCID - Return PEL data in a vector based on the
                     corresponding OpenBMC event log id.
* hostAck - Called when the host has sent the PEL up to the OS,
            which is the final step in the reporting process.
* hostReject - Called when the host has an issue with a PEL, either:
  - The host doesn't have any more room for PELs at this moment.
  - The PEL was malformed.
