lib/horizon: no need to specify keystone v3 to API version

keystone v3 is the default API version in horizon now,
so there is no need to specify it in local_settings.py explicitly.

This commit also makes minor changes in lib/horizon
_horizon_config_set().

* Do not insert a blank line after each setting.
* Use the local variable $file to specify the target file
  consistently.
