Actually, /usr/share/selinux is the standard location for modules to be
placed before running semodule on them, but that isn't directly relevant
to the denial you see below.

Yes, this has shown up before - it indicates that
your /etc/selinux/targeted/modules tree has become mislabeled.  Run
restorecon -R on it.  I think that this has been corrected already in
updates?
