You can get most of the way there via semodule_unpackage and sedismod.
But even that will just give you a low level dump of the rules, not the
original .te sources, so it is better to get the original .te file if
you can. sedismod could use some work to produce output that can be
directly placed in a .te file; it was originally just created as a
developer/debugging tool, not for this purpose.
semodule_unpackage sources have been posted a few times and are now part
of policycoreutils in recent Fedora. sedismod is part of checkpolicy.
