meta: remove consecutive blank lines

Some of them were introduced by mass-removal of S = WORKDIR/git assignments;
rather than try to fix up (or redo) just these, I've run this sed command over
the whole tree:

sed -i -z -E 's/([ \t\f\v\r]*\n){3,}/\n\n/g' `find . -name *.bb -o -name *.inc`

The rationale is that more than one empty line is wasting vertical screen space, and
does nothing for readability.
