[OE-core] [PATCH 2/4] opkg-utils: add update-alternatives PACKAGECONFIG

[Christopher Larson]

From: Christopher Larson <chris_larson at mentor.com>

This lets someone use a different update-alternatives-native provider. Without
this available, they'll step on one another in the sysroot unconditionally,
since we need to build opkg-utils-native for ipk based builds regardless.
