[PATCH] doc: Fix and simplify container image loading description

[Jan Kiszka]

From: Jan Kiszka <jan.kiszka@siemens.com>

The manual was incorrectly referencing 'docker import', rather than what
was also used in the example: only 'docker load' works for the generated
images.

And the proposed command line can be simplified by passing the image
directly to 'docker load'.
