tests: env: skip a few tests if LD_LIBRARY_PATH is set

Browse Source 
* tests/env/env-null.sh: Skip test if LD_LIBRARY_PATH or platform's
equivalent is set, since 'env -i' will unset it which may prevent
programs from running.
* tests/env/env-S.pl: Likewise.
Issue and suggested fix reported by Bruno Haible.
