examples/ipsec-secgw: replace strncpy with strlcpy

Use strlcpy instead of strncpy.
Use strcpy where boundchecks on destination is not needed.

Fixes: 0d547ed037 ("examples/ipsec-secgw: support configuration file")
Fixes: 07b156199f ("examples/ipsec-secgw: fix configuration string termination")
Fixes: a1469c319f ("examples/ipsec-secgw: fix configuration parsing")
