[PATCH v3] dpkg: sbuild allows extra arguments via DPKG_SBUILD_EXTRA_ARGS v3

[roberto.foglietta@linuxteam.org]

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

Sometimes it is necessary to add some extra commands or arguments for
the sbuild process which produces customs packages but creating a class
into an upper layer just for this will create difficulties in managing
the updates from the upstream project.

So, this patch allows setting extra parameters via this variable:

        DPKG_SBUILD_EXTRA_ARGS

v.2: just a single variable and not anymore two of them

v.3: the variable is set in the middle, just in case order matters, it
     is the last of 'setup chroot' and the first of 'final build' commands
