[PATCH] build-appliance-image: Simplify fetch/unpack execution

[Richard Purdie <richard.purdie@linuxfoundation.org>]

This provides a slightly neater way of ensuring fetch/unpack get
executed (image.bbclass marks them as noexec) since I found the
current approach harder to understand at first glance.
