Variables such as SRC_URI which are space-separated may also contain
Python expressions (${@...}) which themselves contain spaces that
shouldn't be split when splitting the value into items. In order to
ensure this we need to use a custom splitting function instead of just
string.split().
This issue could be seen when doing "devtool modify sudo", adding a
commit to the resulting source repository then "devtool update-recipe" -
the Python expression in SRC_URI was being unnecessarily broken onto
multiple lines.
Fixes [YOCTO #8046].
