[OE-core] qemu: backport patches to fix cves breaks qemu-system-native

[Alexey Brodkin]

Hello Kai Kang,

You recent changes in QEMU [1] lead to build failure:
-------------------------------------->8-------------------------------------
# bitbake qemu-system-native
...
| .../build/tmp-glibc/work/x86_64-linux/qemu-system-native/3.1.0-r0/qemu-3.1.0/hw/rdma/rdma_backend.c:316:42: error: 'VENDOR_ERR_INV_NUM_SGE' undeclared (first use in this function)
|          comp_handler(IBV_WC_GENERAL_ERR, VENDOR_ERR_INV_NUM_SGE, ctx);
|                                           ^
-------------------------------------->8-------------------------------------

That's obviously because of meta/recipes-devtools/qemu/qemu/0015-fix-CVE-2018-20124.patch.

I'm wondering if you tried to build QEMU yourself?
