Disable accessible touch exploration by default.

Disable accessible touch exploration by default.

Touch exploration was too buggy in M37, we don't want to launch it.
The plan is to land this change and merge to M37, then revert it to aim for
a launch of touch exploration in M38.

LGTM

Out of curiosity (and probably not for this CL) does this flag need to be added
to chrome/browser/chromeos/login/chrome_restart_request.cc? Some command line
switches are copied from the main command line when logging in to a guest
session.

Thanks, I'll look into OTR.
