Don't use LoadLibraryEx(..., LOAD_LIBRARY_SEARCH_SYSTEM32). It hangs

Browse Source 
Observed running hexchat under X.  For some reason the call to
	LoadLibraryEx(..., LOAD_LIBRARY_SEARCH_SYSTEM32) in dll_load
	hangs when trying to autoload MsgWaitForMultipleObjectsEx in
	select.cc after hexchat forks to run DNS calls.  Dropping the
	call and just using full paths as in 2.3.1 fixes the issue.

	* autoload.cc (dll_load): Drop call to LoadLibraryEx with
	LOAD_LIBRARY_SEARCH_SYSTEM32 flag.
	* wincap.h (wincaps::has_load_lib_search_flags): Remove.
	* wincap.cc (wincaps::has_load_lib_search_flags): Drop handling
	this flag.
