[bug#51838] [PATCH v8 02/41] guix: node-build-system: Add implicit libuv input.

[Liliana Marie Prikler]

* guix/build-system/node.scm (lower): Add the version of libuv
used as an input to the #:node package as an additional implicit
input, so that packages needing libuv always get the correct version.
