kbuild: unify cmd_copy and cmd_shipped
cmd_copy and cmd_shipped have similar functionality. The difference is that cmd_copy uses 'cp' while cmd_shipped 'cat'. Unify them into cmd_copy because this macro name is more intuitive. Going forward, cmd_copy will use 'cat' to avoid the permission issue. I also thought of 'cp --no-preserve=mode' but this option is not mentioned in the POSIX spec [1], so I am keeping the 'cat' command.
