deps: updates term-size to use signed binary

Upstream node is patching `term-size` in order to avoid failing release
builds, see: nodejs/node#32403

Given that npm@6 has to support node6 and that dependency chain is long
enough, along with many major bumps dropping node6 along the way. I
propose we patch it here same as node upstream.
