ipk/rootfs: run sanity test of multilib in parallel

From: "seungkyun.kim" <seungkyun.kim@lge.com>

For multilib type packages, there is an additional temporary
installation before the actual installation. It makes almost doubles
the do_rootfs time if having many multilib type packages.
To avoid this overhead, run sanity test in parallel.
Installing package groups through opkg takes much more time than
copying directory.

Hello,

This reliably fails on the autobuilders:
