sqlite3: Update to 3.8.5 (from 2014-06-04)

Updated SQLite, see: https://sqlite.org/releaselog/3_8_5.html
_Version 3.8.5 fixes more than a dozen obscure bugs. None of these bugs should be a problem for existing applications. Nor do any of the bugs represent a security vulnerability. Nevertheless, upgrading is recommended to prevent future problems._

__I previously updated the sqlite podspec, for the last 5 or so versions but I am not the original spec author, do I have to "claim" this pod if I want to update it in the future? In the last months, nobody cared about updating this pod except myself__
