    tests: Respect the environment by using /usr/bin/env in the shebang
    
    Distributors generally don't like /usr/bin/env [1] because they don't
    want packaged applications to depend on the user's personal PATH.
    However, distributors can, and they do, adjust the shebang to their
    liking. So it seems better to optimize towards respecting any
    customizations that a continuous integration/deployment system or a
    contributor might have made to the environment.
