package/nodejs: bump version to 5.3.0

Replace 4.2.3 with 5.3.0.  5.3.0 is the current Stable release. See
https://nodejs.org/en/blog/release/v5.3.0 for details on the release.

Copied 4.2.3 patched to 5.3.0 with the following exceptions:
 - Removed 0004-fix-arm-vfpv2.patch, committed upstream and included in
   5.3.0.  See https://github.com/nodejs/node/commit/84dea1bd0c
 - Added 0004-Fix-va_list-not-declared.patch, fix for a new bug.  This
   has already been fixed upstream but is not in 5.3.0
