system.hostname item truncates to 8 characters on HP-UX
Happens on HP-UX 11.31 and 11.23 on ia64 and RISC

1. sbin/zabbix_agentd -t system.hostname
   system.hostname [t|ivm-exc-v2]
2. sbin/zabbix_agentd -t agent.version
   agent.version [s|2.0.10]

1. /usr/sbin/zabbix_agentd -t system.hostname
   system.hostname [s|ivm-exc-]
2. /usr/sbin/zabbix_agentd -t agent.version
   agent.version [s|2.2.1]

My assumption it could be introduced in ZBX-5616
