The discovery script generates bad JSON on Ubuntu 14

[cormacj]

The discovery script generates bad JSON on Ubuntu 14:

# ./zbx_zimbra.sh discover
{
-e  "data":[

Changing the shell to /bin/bash makes it work correctly:

root@zimbra:~/zabbix-scripts/zabbix-zimbra# diff -u zbx_zimbra.sh /etc/zabbix/scripts/zbx_zimbra.sh
