www/node: Update 9.11.1_1 -> 10.0.0

Update to the latest major release of Node.js. This release includes
many significant changes, both to Node.js itself and the FreeBSD port.

https://nodejs.org/en/blog/release/v10.0.0/

In particular, Node.js now requires OpenSSL 1.1.0h, so the BUNDLED_SSL
option is enabled by default. It is still possible to disable this
option when using security/openssl-devel (which is currently at 1.1.0h).
Multiple patches are required to get Node.js building with the bundled
OpenSSL library. Only amd64 builds get optimized assembler; all other
archs use non-asm implementations.
