Thierry Bultel bd0b2db231 support/testing/tests/fs/test_cpio.py: new runtime test
It includes a simple test for the full cpio image, and a test of the
dracut image. To validate that the dracut image is a subset of the full
image, 'pv' is added to the image, and the test verifies that pv is not
part of the image. Note that the real rootfs is not mounted at the
moment, so pv is never available in the running image.

Systemd and other init systems are currently untested.
