bug#22946: 25.1.50; NON_BLOCKING_CONNECT is obsolete

[Lars Magne Ingebrigtsen]

According to Paul and Eli, Emacs no longer have any build targets where
NON_BLOCKING_CONNECT (in process.c) is undefined.  So the relevant code
paths should be cleaned up.

(I'm just mentioning it here so that we don't forget.)
