nodejs: security bump to version 6.11.5

Fixes CVE-2017-14919 - In zlib v1.2.9, a change was made that causes an
error to be raised when a raw deflate stream is initialized with windowBits
set to 8.  On some versions this crashes Node and you cannot recover from
it, while on some versions it throws an exception.  Node.js will now
gracefully set windowBits to 9 replicating the legacy behavior to avoid a
DOS vector.

For more details, see the announcement:

Drop 0002-inspector-don-t-build-when-ssl-support-is-disabled.patch as that
is now upstream:

https://github.com/nodejs/node/commit/ba23506419

And refresh the other patches.
