build: cleanup: define MSG_DONTWAIT/MSG_NO_SIGNAL locally

Define MSG_DONTWAIT and MSG_NO_SIGNAL in the implementation files that
use them (`net.cpp` and `netbase.cpp`), instead of compat.h which is
included all over the place.

This avoids putting them in the global namespace, as defining them as 0
is a hack that works for our specific usage, but it is not a general
solution.

Also makes sure they are defined only once so the `!defined(MSG_x)` guard can go.
