[OE-core] [PATCH 2/3] package(rootfs)_ipk.bbclass: support multilib in opkg backend.

[Richard Purdie]

From: Lianhao Lu <lianhao.lu at intel.com>

Support install multiple multilib in opkg backend.

The installation is done in 3 phases.

Phase 1: install normal packages to IMAGE_ROOTFS.

Phase 2: install multilib packages under MULTILIB_TEMP_ROOTFS. Packages
belongs to the same multilib arch would be installed to a unique
directory.

Phase 3: check file confliction between IMAGE_ROOTFS and
MULTILIB_TEMP_ROOTFS, install multilib packages to IMAGE_ROOTFS only if
the sanity check passed.
