Description:

Elasticsearch fails to start.
It tries to access unexisting directory '/usr/share/elasticsearch/bin'
Log reports : java.lang.IllegalStateException: Unable to access 'path.home' (/usr/share/elasticsearch/bin)

Steps to reproduce:
> pacman -S elasticsearch
> systemctl start elasticsearch

Possibles fixes :
* Option 1 :
Add an empty 'bin' directory in '/usr/share/elasticsearch/'
* Option 2 :
Put 'elasticsearch' and 'elasticsearch-plugin' in '/usr/share/elasticsearch/bin/'
Create symlinks from '/bin'
