[PATCH v4] image: make sure do_rootfs_finalize can run multiple times, v4

[roberto.foglietta@linuxteam.org]

From: "Roberto A. Foglietta" <roberto.foglietta@gmail.com>

image: make sure do_rootfs_finalize can run multiple times, v4

The rootfs_finalize task currently cannot be re-executed, as it moves
the sources-list into bootstrap.list. As this only has to be done once,
it is not required on subsequent executions. To fix the rebuild issue,
we simply ignore the return code of the mv statement.

v2: essential code, only

v3: code above the fix, rationalisation

v4: like v3 but with the description provided by Felix Moessbauer
