setools 4.2.0 dropped support for Python 2. On systems where
/usr/bin/python is Python 2, several tools are now broken because of
this. Update the shebang of these tools to /usr/bin/python3.
For future reference, as semanage/seobject.py, sepolicy and sepolgen
import setools, every program that uses one of these modules need to be
run with Python 3. The following programs do not use any of these
modules so their shebangs have not been modified:
dbus/selinux_server.py
libsemanage/utils/semanage_migrate_store
mcstrans/share/util/mlscolor-test
mcstrans/share/util/mlstrans-test
sandbox/start

Aliases are not used in the selinux database. When user enters a type
alias as a parameter it should be converted to the corresponding type
in order to be processed correctly further in the userspace logic.
Fixes e.g.:
\#sepolicy transition -s phpfpm_t
/* where phpfpm_t is a type alias of httpd_t */
