Fix discard_graph_edges_test on Mac.

The assertion in line #235 passes on Linux if the
limit is 9, on Darwin if it is 10.

Commenting out the code in BazelRulesModule.java
that automatically loads the sh_configure() rule
which instantiates @local_config_sh makes the test
pass with the old limit (8).
