rootfs_ipk: allow do_populate_sdk in parallel to do_rootfs

Switch do_populate_sdk for the ipk package manager to use a separate target
opkg config file and separate the lockfiles restricting do_rootfs and
do_populate_sdk from running in parallel.

This way if an image recipe includes a dependency to do_populate_sdk by
default then it will run in parallel to do_rootfs saving time compared to the
sequential execution.
