Add henrik.smiding@intel.com to trybots whitelist
Add henrik.smiding@intel.com to trybots whitelist

IIRC, previously Chromium masters would invalidate trybot requests from our external contributors (which did not have chromium.org accounts), this appears to have been fixed. I validated that a request from a user in the whitelist worked and a request from a user not in the whitelist was rejected by our masters.

Will require all masters to be restarted.
