Vadim Ushakov 5c9c7c8b1f Fix overflow of "running" value in getstat()
It seems in some cases procs_running field of /proc/stat can contain 0 even if vmstat itself is running. At least this can be reproduced on Linux 3.9.3 compiled with BFS scheduler.

Since getstat() decrements value of procs_running by 1, we get overflow:

$ vmstat 1

COMPATIBILITY

    This code is intended for use with Linux 2.6.xx, 3.x and
    hopefully all future kernels.

INSTALLATION

    If you are using git version of the project you need extra step.

    ./autogen.sh

    After that, and everyone using .tar.xz version of procps-ng, can
    do normal build.  Read './configure --help' to select options for
    your needs.

    ./configure
    make
    make install

    If you have DejaGNU installed you can run optional test suite.

    make check

PACKAGING

    If you are a downstream maintainer (packager) for a Linux
    distribution, please avoid causing troubles.  This section
    applies to you.

    Avoid maintaining distribution specific patches.  Send your
    patches to upstream, where they are at least reviewed, if not
    included.

    Please forward bug reports. If your bug database is public and
    busy enough to bother with, please make this known.  Follow
    Debian's lead in making the bug database easy to comment on via
    email without need for an account.

    For normal packages, ensure that you do not add debugging flags
    to the CFLAGS variable.
