package/dpdk: fix example build issue when libvirt is present

Browse Source 
When libvirt is present before DPDK is built, some additional examples
are compiled. One of them fails to build due to a missing <stdlib.h>
include. Let's import a patch from OpenSuse, that we have submitted
upstream, to fix this issue.

We couldn't find any autobuilder failure for this issue, but the
following defconfig allows to reproduce the failure:

BR2_aarch64=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN=y
BR2_TOOLCHAIN_EXTERNAL_BOOTLIN_AARCH64_GLIBC_STABLE=y
BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_EUDEV=y
BR2_PACKAGE_DPDK=y
BR2_PACKAGE_DPDK_EXAMPLES=y
BR2_PACKAGE_LIBVIRT=y

The problem exists since DPDK v19.11, so it has been in Buildroot
since DPDK was introduced in commit
d17d1b6bde.
