vlan: use update-alternatives for vconfig

Busybox also provides the command 'vconfig' when CONFIG_VCONFIG is
enabled.

Busybox has a priority of 50.

Prior to the patch running

    bitbake core-image-minimal

produced the warnings

    WARNING: core-image-minimal-1.0-r0 do_rootfs: busybox.postinst returned 1, marking as unpacked only, configuration required on target.
    WARNING: core-image-minimal-1.0-r0 do_rootfs: Intentionally failing postinstall scriptlets of ['busybox'] to defer them to first boot is deprecated. Please place them into pkg_postinst_ontarget_${PN} ().
    If deferring to first boot wasn't the intent, then scriptlet failure may mean an issue in the recipe, or a regression elsewhere.
    Details of the failure are in /path/to/poky/build/tmp-glibc/work/qemux86-oe-linux/core-image-minimal/1.0-r0/temp/log.do_rootfs.
