app/procinfo: use strlcpy for copying string

Browse source 
Replaced strncpy and strcpy with strlcpy.
Also replaced snprintf with strlcpy where applicable.
Using strlcpy is safe practice when copying strings, as it will include
a null terminator.

Fixes: 2deb6b5246 ("app/procinfo: add collectd format and host id")
Fixes: 8a37f37fc2 ("app/procinfo: add --show-port")
