problems with ubuntu installation

[nobless]

1. emonhub not launching in ubuntu because of these:
   Requires=var-log.mount
   After=var-log.mount network.target
   file: /etc/systemd/system/emonhub.service

2. /opt/openenergymonitor/EmonScripts/install/config.ini file lacks emoncms_modules[config]=master
   so if install_emonhub=true it still does not install in ubuntu.

3. /opt/openenergymonitor/emonhub/install.sh i don't think that bluetooth modules is needed for ubuntu installation:
   bluetooth libbluetooth-dev
   now:

sudo apt-get install -y python3-serial python3-configobj python3-pip python3-pymodbus bluetooth libbluetooth-dev
sudo pip3 install paho-mqtt requests pybluez

if [ "$emonSD_pi_env" = "1" ]; then
...

improvement:

sudo apt-get install -y python3-serial python3-configobj python3-pip python3-pymodbus
sudo pip3 install paho-mqtt requests

if [ "$emonSD_pi_env" = "1" ]; then
sudo apt-get install -y  bluetooth libbluetooth-dev
sudo pip3 install pybluez
...
