We are going to merge this in near few days in spite of an open
question left in discussion. The reasons:

1. It passes internal CI (dev/fast/full).

2. It was useful in case of 'meta-iot2050' downstream for rewriting
"npm.bbclass" in order not to use buildchroot.bbclass (that is going to
be deleted with "Imager schroot migration" patchset that is to be
merged soon too.
