Revert 250439 "Mojo: Add a public/environment/test_support.h."

This isn't quite right. It breaks (on a Linux shared library build)
mojo_shell_unittests at runtime. The stuff in test_support.h also
differs considerably from other stuff in environment/ (it's not
something chosen by the app), so it doesn't belong there. Hmmm.
