Validation fails with valid UUID 3

[YegorMedvedev]

Context

• node version: v8.9.2
• joi version: 13.4.0
• environment (node, browser): node
• used with (hapi, standalone, ...): standalone

What are you trying to achieve or the steps to reproduce ?

Joi validate function fails on UUID v3, when UUID version passed to function.

For reproduction, please, follow the next script:

const joi = require("joi")

const uuid = "bfbf15ac-7388-3cf3-6720-19fde31a1711";
joi.validate(uuid, joi.string().guid()) // passes
joi.validate(uuid, joi.string().guid({version: ["uuidv1", "uuidv2", "uuidv3", "uuidv4", "uuidv5"]})) // fails

What did you expect ?

Expected behaviour, that validate function with version will not fail.

That's because the uuid is not compatible with any modern uuid version. It has an incorrect variant. I am not sure why the default regex allows it but I'll look into it.
