[PATCH v2 3/5] zlib: Remove files that should certainly not be checked in

["Luke T. Shumaker" <lukeshu@lukeshu.com>]

The *.obj files are compiled binaries that should have been
.gitignore'd (and so also add an `*.obj` entry to .gitignore).

zlib/example.c and zlib/minigzip.c are outdated duplicates of
zlib/test/example.c and zlib/test/minigzip.c

My justification believing that the *.obj files should be removed and
ignored is as follows:

 - AFAICT, these files are not used by binutils-gdb.

 - As shown in the final commit of this patch series, the zlib
   directory is perfectly re-created *except for these files* by
   extracting zlib-1.2.12.tar over zlib-1.2.10.tar.  Neither of those
   tarballs include any .obj files.

 - These files were first added to binutils-gdb.git from gcc.git in
   5ca28f79288 (Import zlib from GCC, H.J. Lu, 2015-03-13), which is
   is a faithful (except for some $Id$ mangling) of zlib-1.2.7.tar.
   That tarball does not include any .obj files either.

 - However, zlib tarballs did include some .obj files in the
   v1.2.[0-3] range.

 - And whadayaknow, the .obj files were first added to gcc.git in
   303ae446cf2a (Initial revision, Tom Tromey, 2005-09-12), which
   bundled zlib-1.2.1.tar (which as I just said is indeed one of the
   archives that includes .obj files).

 - Ever since being first checked in to gcc.git/binutils-gdb.git, the
   .obj files have never once been updated, even though the associated
   assembly source code has had substantial revisions.

---
v2:
- Add *.obj to .gitignore.
- Add justification for my beliefs to the commit message.
