[oe] [meta-networking][PATCH] libowfat: fix sdk installation

[André Draszik]

From: André Draszik <andre.draszik at jci.com>

Building an SDK with this included fails:
 * calculate_dependencies_for: Cannot satisfy the following dependencies for ncp-dev:
 * 	libowfat (= 0.32-r0) *
 * opkg_solver_install: Cannot install package ncp-dev.

libowfat only provides a static library, so there no
${PN} package is created by default.

Add ALLOW_EMPTY_${PN} = "1" to allow creation of an empty
${PN} package.
