cp/mv: add -T.
The kernel script scripts/kconfig/merge_config.sh uses cp -T.
(Also sort the options into alphabetical order while adding -T, so that
eyeball binary search actually works when trying to find an option! Oddly,
they all show in reverse order because there's a bug in the help text
generator, but that's a problem for another day...)
