[PATCH] scripts/bloat-o-meter: fix SIGPIPE

[Alexey Dobriyan]

Fix piping output to a program which quickly exits (read: head -n1)


	$ ./scripts/bloat-o-meter ../vmlinux-000 ../obj/vmlinux | head -n1
	add/remove: 0/0 grow/shrink: 9/60 up/down: 124/-305 (-181)
	close failed in file object destructor:
	sys.excepthook is missing
	lost sys.stderr
