sd-boot: trigger to record further logs to tcg 2.0 final event log area (#4302)
According to TCG EFI Protocol Specification for TPM 2.0 family,
all events generated after the invocation of EFI_TCG2_GET_EVENT_LOG
shall be stored in an instance of an EFI_CONFIGURATION_TABLE aka
EFI TCG 2.0 final events table. Hence, it is necessary to trigger the
internal switch through calling get_event_log() in order to allow
to retrieve the logs from OS runtime.

> I've looked at EDK2 and indeed log entry is added to FinalEventsTable only after
> EFI_TCG2_PROTOCOL.GetEventLog was called[1][2]. Also, same patch was currently
> merged to shim by Peter Jones [3].
