[5.1] lit.cfg: Respect the DYLD_LIBRARY_PATH restrictions when not using %target-run

Some test cases use something like
```
config.target_run_simple_swift = (
        '%%empty-directory(%%t) && '
        '%s %s %%s -o %%t/a.out -module-name main  && '
        '%s %%t/a.out &&'
        '%s %%t/a.out’
```
That does not respect the %target-run DYLD_LIBRARY_PATH for choosing the just built libraries and/or OS libraries.
This PR respects said library path in such situations
