Update Requests library to version 2.0.6

[jrf]

Requests 2.0.6 has just been released with a tiny bug fix which is relevant for WP.

Full details:

• ​https://github.com/WordPress/Requests/releases/tag/v2.0.6
• ​https://github.com/WordPress/Requests/compare/v2.0.5...v2.0.6

I would recommend an update (with the exception of the certificate bundle for which WP has its own version).
