Fix uwsgi keystone

The uwsgi keystone jobs are failing with an error like

 + devstack/functions-common:_run_process:L1391:   setsid uwsgi /etc/keystone/keystone-uwsgi-admin.ini
 + devstack/functions-common:_run_process:L1395:   exit 0
 execvp: No such file or directory

I think this is because uwsgi isn't installed on the images. The fix
is to pip install it.

Also, use the full path to the uwsgi executable (even though execvp
is used) because eventlet (calling keystone-all) does.

Also, the uwsgi process wasn't shutting down on ./unstack.sh. This
is worked around by not running master process.
