Colin Walters e666a5b350 vmcheck: Support VMCHECK_INSTTREE
I need to build ostree from git too.  So now my workflow is:

```
export insttree=/srv/walters/tmp/rootfs
cd ostree
make && make install DESTDIR=${insttree}
cd rpm-ostree
make && make install DESTDIR=${insttree}
env VMCHECK_INSTTREE=${insttree} make vmoverlay
```
