package/nodejs: security bump to version 12.20.1

Fixes the following security issues:

- CVE-2020-8265: use-after-free in TLSWrap (High) Affected Node.js versions
  are vulnerable to a use-after-free bug in its TLS implementation.  When
  writing to a TLS enabled socket, node::StreamBase::Write calls
  node::TLSWrap::DoWrite with a freshly allocated WriteWrap object as first
  argument.  If the DoWrite method does not return an error, this object is
  passed back to the caller as part of a StreamWriteResult structure.  This
  may be exploited to corrupt memory leading to a Denial of Service or
  potentially other exploits

- CVE-2020-8287: HTTP Request Smuggling in nodejs Affected versions of
  Node.js allow two copies of a header field in a http request.  For
  example, two Transfer-Encoding header fields.  In this case Node.js
  identifies the first header field and ignores the second.  This can lead
  to HTTP Request Smuggling

- CVE-2020-1971: OpenSSL - EDIPARTYNAME NULL pointer de-reference (High)
  This is a vulnerability in OpenSSL which may be exploited through Node.js.
