uebayasi c260945c48 Don't reserve space (128) on signal stack for unknown reasons; the actual
space for struct sigframe_siginfo (+ alignment) is allocated just below.

Confirmed by the following tests:

	tests/lib/libc/gen/t_siginfo
	tests/lib/libc/sys/t_sigtimedwait
	tests/lib/libc/sys/t_sigaction
	tests/lib/libc/sys/t_sigqueue
