guest kernel needs 64 bytes of DRAM per 4K page of emulated PMEM, hence the
image size should be as small as possible to reduce the container's memory
footprint. The image size is recalculated automatically if it's too small
to contain the rootfs.

Add new options to rootfs.sh: -l prints the list of all distros,
-t retrieves a subset of the distro configuration from config.sh
for testing purpose.

Rework test_images.sh and Makefile to allow building artifacts in
parallel for faster tests execution.
Add new targets to Makefile ({rootfs,image,initrd}-<distro name>).

Update Makefile so that build artifacts are actually tracked as make
targets. This is to enforce a strict prerequisite ordering and better
handle parallel builds.
Fixes: #157
Signed-off-by: Marco Vedovati <mvedovati@suse.com>
Updated the `Makefile` to provide the following new targets:
```
make test # Run all tests.
make test-image-only # Only run image tests.
make test-initrd-only # Only run initrd tests.
```

Create a YAML metadata file inside the rootfs image
containing information about the environment:
```
/var/lib/osbuilder/osbuilder.yaml
```
Example contents:
```

This change adds a new `-o` option to `rootfs.sh` for
specifying the version of osbuilder to the rootfs builder.
Fixes#35.
