MAN 7 Signal part: SO_RCVTIMEO should be SO_SNDTIMEO

[zgjsxx]

man 7 signal, the below part has an error:

• "Input" socket interfaces, when a timeout (SO_RCVTIMEO) has been set on the socket using setsockopt(2): accept(2), recv(2), recvfrom(2), recvmmsg(2) (also with a non-NULL timeout argument), and recvmsg(2).

• "Output" socket interfaces, when a timeout (SO_RCVTIMEO) has been set on the socket using setsockopt(2): connect(2), send(2), sendto(2), and sendmsg(2).

I suppose that for Output socket interfaces, the option should be SO_SNDTIMEO not SO_RCVTIMEO.
Please fix it.
