civetweb: allow the OS to set the stack size (#445597)

    # The civetweb unit tests rely on downloading their fork of libcheck.

    "-DCIVETWEB_BUILD_TESTING=OFF"

    # The default stack size in civetweb is 102400 (see the CMakeLists [1]).

    # This can lead to stack overflows even in basic usage;

    # Setting this value to 0 lets the OS choose the stack size instead, which results in a more suitable value.
