Title: make service environment file optional

Currently, the systemd service fails to start if /etc/conf.d/ympd doesn't exist.

According to the [systemd doc](http://www.freedesktop.org/software/systemd/man/systemd.exec.html#EnvironmentFile=), prefixing the filename with a `-` makes it optional so the service can start with the default value when there is no config file.
