docs: avoid overwrite of LD_LIBRARY_PATH during basic testing

The LD_LIBRARY_PATH environment variable could be already defined so
we extend it and restore it rather than just overwriting it.

v2:
 - Unset the __old_ld helper variable when we are done with it.
 - Corrected test for and escaping of variables (Eric).

v3: Remove unneeded variable (Emil).
