configs: enable INET_DIAG

iproute2 suite, including ss, depends on INET_DIAG.

This patch enables CONFIG_INET_DIAG and a set of
protocol specific configs depend on CONFIG_INET_DIAG,
such as CONFIG_INET_TCP_DIAG, CONFIG_INET_UDP_DIAG,
CONFIG_INET_RAW_DIAG and CONFIG_INET_SCTP_DIAG.

These configs are all set as module.
