net/ping: utils ping should depends on ipv4

[HedongGao]

Summary

ping tool depends on NET-IPV4, and all dependencies should be added in Kconfig.

Impact

ping tool compile.

Testing

Enable the 'system ping' compilation configuration, disable the 'NET-IPV4' compilation configuration, and then start compiling. The following error message appears:

Add relationship for SYSTEM_PING, then these error information disapeared.
