net-p2p/deluge-cli: correct deluge_web rc-script

From the PR:
The rc.d script for deluge_web outright disrespects a user's home directory and
instead tries to execute against hardcoded /home/${deluge_web_user} paths. This
is invalid and dangerous behavior. When running as a user, the user's home
directory must be respected. The attached patch fixes this behavior as a break-fix.
