[oe] [meta-oe][PATCH] nodejs: allow use of system c-ares (and make default)

[André Draszik]

Use system c-ares via PACKAGECONFIG by default. So far,
nodejs had been built using its embedded copy of c-ares,
which we generally try to avoid, for the known reasons
(independent updates, cve & license checks, etc).

Notes:
* otherwise nodejs uses its bundled version of c-ares
* the PACKAGECONFIG variable is 'ares' so as to be in
  line with other uses of this (wget & curl recipes in
  OE core)
