Update systemd unit file for virtualenv (home-assistant#1785)

asbach · fabaff · commit c1aeb7ed5564 · 2017-01-17T08:02:12.000+01:00
The current systemd unit file will provoke an error because the 'ExecPre' line calls a shell built-in function and all systemd Execs need to use an absolute path. the proposed change sets the python environment using the provided 'Environment' calls as used by systemd.
