Since commit
7b9fd5d1c9
tsm-client no longer produces working binaries
(discovered with bisection).
Instead, calling the command line client `dsmc`
just produces the error
> error while loading shared libraries: libtsmxerces-depdom.so.28: cannot open shared object file: No such file or directory

The commit given above rewrote the `autoPatchelfHook`.
The new hook still calls `patchelf` to actually
modify binary files, but the discovery of
shared libraries apparently got changed.
Thorough investigation of all `patchelf` calls in the
old and new autoPatchelfHook showed that all files are
treated equally up the the files
* $out/opt/tivoli/tsm/client/api/bin64/libtsmxerces-depdom.so.28.0
* $out/opt/tivoli/tsm/client/api/bin64/libxmlutil-8.1.13.0.so
where the new autoPatchelf implementation replaced `$out/lib`
with `$out/opt/tivoli/tsm/client/api/bin64` in the rpath.
I failed to see *why* the new algorithm does
that, or if that might be considered a bug.
The `tsm-client` package has some confusing symlink
structure which certainly might confuse `autoPatchelfHook`.
The following ideas to "restore" the old behaviour
of `autoPatchelfHook` failed to produce a working package:
* add "$out" or "${placeholder "out"}" to `runtimeDependencies`
* use `addAutoPatchelfSearchPath` with `$out/lib` or
another so-file-containing directory
The commit at hand fixes the issue by directly adding `$out/lib`
to the rpath of all shared libraries in that directory.
This has to be done *after* `autoPatchelf` got executed.
To accomplish this, we disable auto-calling `autoPatchelf`
(it would run after `postFixup`) and instead call it
manually in `postFixup`, just before we patch the rpath by hand.
