[dev-context] Typo in data-crl and data-sch

Hi, There was a pull request on the github mirror of context sources about a typo in the curl template in data-crl.lua and data-sch.lua https://github.com/contextgarden/context-mirror/pull/1/commits/02e9affa92bc7... There should be no space in `-- insecure` flag. Aditya
