[OE-core] [PATCH v3 09/17] devtool/standard.py: npm: exclude the node_modules directory

[Jean-Marie LEMETAYER]

If 'devtool add' was executed without the '--no-git' option a git
repository have been initialized in the source directory in order to
check if the sources stay unchanged after the 'devtool build' command.
The 'devtool finish' command will fail if any modification is found.

As the node_modules directory is added to the source tree in order to
manage the dependency license, it needs to be explicitly excluded from
this git repository.
