efi: call get_event_log before ExitBootServices
With TPM 2.0 specification, the event logs may only be accessible by calling an EFI Boot Service. Modify the EFI stub to copy the log area to a new Linux-specific EFI configuration table so it remains accessible once booted. When calling this service, it is possible to specify the expected format of the logs: TPM 1.2 (SHA1) or TPM 2.0 ("Crypto Agile"). For now, only the first format is retrieved.
