Hostname and PID are output as a message prefix in many places in our code. Their printf-formats were either `[%s:%d]` or `[%s:%05d]`. This commit changes `[%s:%d]` to `[%s:%05d]`. The latter was more widely used in our code (including OPAL output system and the signal handler). Signed-off-by: KAWASHIMA Takahiro <t-kawashima@jp.fujitsu.com>
