[bitbake-devel] [PATCH v3 5/7] fetch2/npm.py: unpack the dependencies in a node_modules directory

[Jean-Marie LEMETAYER]

This commit unpacks the dependencies in a node_modules directory in the
source tree. This is needed to allow license file management for all the
dependencies. This way the license files of the dependencies can be
tracked in the LIC_FILES_CHKSUM variable.
