Selinux depreciated selinux/flask.h and selinux/av_permissions.h

[rootinchase]

Failse to compile after selinux depreciated the following files:

• selinux/flask.h
• selinux/av_permissions.h

Here is the commit that did it. https://github.com/SELinuxProject/selinux/commit/76913d8adb61b5afe28fd3b4ce91feab29e284dd

In the commit they do say what to do instead.

To fix, replace flask.h calls with string_to_security_class(), and av_permissions.h with string_to_av_perm().
