fetch2/npm: add noverify parameter to skip lockdown/shrinkwrap

When fetching source for the first time within scripts such as
OpenEmbedded's recipetool, we don't want to be showing warnings about
NPM_SHRINKWRAP or NPM_LOCKDOWN not being set since there's no way we
could have set them in advance. Previously we were using
ud.ignore_checksums to suppress these but since we are now using a more
standard task-based path to fetch the source, we need to disable these
through the metadata. Look for a "noverify" parameter set on the npm URL
and skip the checks if it is set to "1".
