bsd_signal was added in XPG4.2, so should be declared for
__USE_XOPEN_EXTENDED, instead of the present __USE_XOPEN condition.
This patch fixes the condition accordingly.

Tested for x86_64.  Because of other namespace problems this does not
allow any conform/ XFAILs to be removed.

	[BZ #21552]
	* signal/signal.h (bsd_signal): Declare if [__USE_XOPEN_EXTENDED],
	not [__USE_XOPEN].
