cubieboard: mkcubiecard: use the right command for checking user privilege
On some shell environments the EUID variable, which checks the user id, is not defined. Use `id -u` instead. This patch mutes the following error: ./board/cubietech/cubieboard/mkcubiecard.sh: 31: [: -ne: unexpected operator Signed-off-by: Andi Shyti <andi@etezian.org> Reviewed-by: Arvid Picciani <aep@exys.org> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
