Subject: [PATCH] Set BUILDAH_ISOLATION env var

By default, `buildah` creates its working containers using kernel
namespaces.  When it is running in a container itself, this is not
possible, so it must use a plain `chroot`.  Setting this environment
variable will ensure that it does this by default, without having to
explicitly pass `--isolation chroot` on the command line.
