I unset LIBGL_ALWAYS_INDIRECT and set only LIBGL_ALWAYS_SOFTWARE but
the output was still the same.

This means you also have LIBGL_ALWAYS_INDIRECT set, which means the
server is creating the GLX context. I don't think you can easily
control which dri driver the server opens, but I might be wrong. So,
if you have LIBGL_ALWAYS_SOFTWARE set and LIBGL_ALWAYS_INDIRECT unset,
then you should get direct rendering with the swrast.
To review,
LIBGL_ALWAYS_INDIRECT: use the X server's GLX context. This used to
mean you'd also get software rendering, but with AIGLX you'll probably
get the hardware DRI driver.
LIBGL_ALWAYS_SOFTWARE: tell libGL to use the software renderer. This
only works with direct rendering because otherwise you're getting the
DRI driver that the X server opened, and it's not controlled by this
variable.
