build: check MSG_NOSIGNAL directly, drop detection and interim macro

Drop detecting it at configure time, along with the interim macro
`HAVE_MSG_NOSIGNAL`. There is no longer a reason for this workaround,
and allows to save the work at configure time and simplify.

Also say in a comment that `sys/socket.h` is defining this macro.

Follow-up to 77b3bc239d

Closes #20559
