Call init script helpers with explicit path (./)

The provided OpenVPN init scripts scan /etc/openvpn for *.conf and run
an OpenVPN process for each, and if a .sh script with the same base name
exists, this is run before openvpn.  Change from running "$name.sh" to
"./$name.sh" - depending on the shell used, the script won't be found
otherwise, and ensuring that the script isn't searched in $PATH is the
right thing anyway.
