www/node[45]: work around build breakages due to include path ordering

Add a post-configure step to strip out all occurrences of
-I${LOCALBASE}/include. Rely instead on USES+=localbase to tell the
compiler where to find includes from external dependencies.

After r416894, node.js builds will use external dependencies instead of
bundled ones. Fallout from this changes includes several build
breakages. All come from the fact that the node-gyp build process adds
-I${LOCALBASE}/include to CFLAGS before all others, including its own
bundled dependencies. This causes the build to incorrectly pick up
include files from any packages in ${LOCALBASE}, rather than the bundled
libraries as intended.

www/node, www/node[45]: Depend on devel/icu instead of the bundled icu-small

Prefer external libraries to the ones bundled with node.

Do not statically link bundled libraries into node.js. It requires
openssl 1.0.2, so pull that in from ports when the base version is not
new enough. While all versions use c-ares, only www/node has a configure
knob to enable building against an unbundled version. All other
dependencies are specified in www/node/common.mk and used by all 3
ports.

node cannot build against LibreSSL, so if it's the chosen SSL provider,
the BUNDLED_SSL option must be enabled.

The www/node010 and www/node012 ports have not been done since both are
deprecated and have very old bundled dependencies that are not available
in ports.

New port: www/node5, to ease migration from node-5.x to node-6.x

This new major version of Node.js delivers significant improvements
in performance, reliability, usability and security. Module loading
is nearly four times faster than in Node.js v4, tests and documentation
have seen significant improvements, usability of the Buffer and
File System APIs have been improved, and Node.js now supports 93%
of ES6 language features, thanks to V8 version 5.0.

The full changelog is available on Github:

For node5:
node.js v5.x will only be supported for a few months to give people
time to move to v6. This new port is marked as deprecated with an
expiration date of July 1, allowing all of May and June to transition.
