[fixincludes patch] Fix sys/signal.h on svr4 systems in regular fixincludes

[Nathanael Nerode]

This does the right thing on Sequent's DYNIX/ptx, and fails to trigger on
Linux.  OK for mainline?

	* fixinc/inclhack.def (svr4_sighandler_type): New fix, ported
	from fixinc.svr4.
	* fixinc/fixincl.x: Regenerate.
	* fixinc/tests/base/sys/signal.h: Regenerate.
