ping: add -I for bind device

[wangchen61698]

Note: Please adhere to Contributing Guidelines.

Summary

1. Add -I option to specify the network device to use for sending ICMP echo requests. This allows users to explicitly bind ping to a specific network interface, which is particularly useful in multi-homed systems with multiple network interfaces.
2. Initialize info.devname to NULL to solve the problem of the SO-BINDTODEVICE property being set incorrectly in the icmp_ping function

Impact
