Title: node: set npm loglevel temporarily for postinstall

This change avoids setting 'loglevel' in the npm builtin npmrc file.
Setting the log level to 'verbose' is intended only for the postinstall
step and is not desired to be persistent.

Motivation for this change can be found at SHA: e2dc359.
