[opensuse-buildservice] [PATCH] Add --build-abuild-id to osc and build

When building locally in a qemu/chroot and debugging I find I want to edit the files in the chroot from my desktop gui editor but they're all owned by 399:399. This pair of patches allows me to set the uid:gid to match my local user and eases this process. usage is: build --build-abuild-id uid:gid or more usually: osc build --build-abuild-id 500:500 osc also accepts (and extends the default) .oscrc settings: build-abuild-id = 500:500 It only supports numeric ids.
