sdk.py: fix conflicts of packages

If packages are conveyed to smart to install at the same time,
conflicts will not happen.
Try to install packages into sdk image at the same time.

This patch is not so perfect. For example,
  IMAGE_INSTALL += "lib32-ncurses"
  IMAGE_INSTALL += "ncurses-dev"
 ncurses-dev and lib32-ncurses-dev will have conflicts during packages installation.
