proc: don't report kernel addresses in /proc/<pid>/stack
This just changes the file to report them as zero, although maybe even
that could be removed. I checked, and at least procps doesn't actually
seem to parse the 'stack' file at all.
And since the file doesn't necessarily even exist (it requires
CONFIG_STACKTRACE), possibly other tools don't really use it either.
That said, in case somebody parses it with tools, just having that zero
there should keep such tools happy.
