Jim Warner 526bc5dfa9 library: avoid SEGV if file2str should read zero bytes 
When utility buffers were introduced for file2str read
requests, a subtle change was inadvertently introduced
such that a read of zero no longer returns a -1 value.

This commit ensures that zero bytes read returns a -1.

And although the solution differs from a merge request
submitted by sergey.senozhatsky@gmail.com, a thank you
is offered for revealing this potential abend problem.

README 

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

HOW TO CONTRIBUTE

    See Documentation/BUGS file.

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.
