[COMMITED] ada: Remove socket definitions for ancient MinGW

[Marc Poulhiès]

From: Piotr Trojanek <trojanek@adacore.com>

Modern MinGW defines _WIN32_WINNT as 0xa00, so there is no need go guard
against it being lower than 0x0600 or setting it to 0x0501.

gcc/ada/

	* gsocket.h: Remove redefinition of _WIN32_WINNT.
	* mingw32.h: Remove conditional definition of _WIN32_WINNT.

Tested on x86_64-pc-linux-gnu, committed on master.
