    test-utils: Clarify meaning of an environment variable
    
    SOUP_TESTS_IN_MAKE_CHECK used to be used for the Autotools build system.
    I mistakenly thought it was a way to skip the Apache-dependent tests
    during `make check`, but in fact the Autotools build system used to
    start a single instance of Apache, then run all the tests against that
    single instance, and finally shut it down.
    
    This mechanism is currently unused, but resurrecting it might be one way
    to avoid GNOME/libsoup#175.
