elog: Get rid of the staging_header variable.

The header is at the start of the log. There's no reason to either keep a
    seperate pointer to it, or to keep a copy of it in some other bit of memory.

Built and booted on Link and used 'mosys eventlog list' to list the
    contents of the log. Ran

for x in $(seq 1 2000); do
      cat elog.event.kernel_clean > /sys/firmware/gsmi/append_to_eventlog;
    done

And ran mosys eventlog list again to verify that the log had been shrunk
    correctly.
