kernel-install.eclass: fix objcopy overwriting uki
>From the manual:
If you do not specify outfile, objcopy creates a temporary file and
destructively renames the result with the name of infile.
We don't want that. Unfortunately we cannot use /dev/null as dump, objcopy
complains, so we dump it in T instead.
