[PATCH 06/11] lib/bb/siggen: don't show unchanged runtaskdeps list

[Paul Eggleton <paul.eggleton@linux.intel.com>]

If the runtaskdeps list hasn't actually changed (but the signatures of
some of the tasks did) then it doesn't make sense to print out the old
and new lists as they are both the same and may be very long, e.g. for
do_rootfs in OE.
