[bitbake-devel] [PATCH 3/3] fetch2/npm: fix handling of os field

[Paul Eggleton]

When I originally added this check I didn't quite understand how the
values in this field should be expressed - it seems from reading the
documentation if there is an entry starting with '!' then the list is
a blacklist and we shouldn't expect "linux" to be in the list, or we'll
end up skipping important dependencies.

This fixes fetching the "statsd" npm package.

Fixes [YOCTO #10760].
