Bug 1919402

## Description of problem:

Configuring RHEL8 as described here:

https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/6/html/security_guide/sec-configuring_pam_for_auditing#sec-configuring_pam_tty_audit

resulted in AVC/Deny and filled log files with

time->Mon Jan 11 10:05:01 2021
type=PROCTITLE msg=audit(1610355901.401:35527): proctitle="(systemd)"

##Version-Release number of selected component (if applicable):

# rpm -q pam systemd selinux-policy
pam-1.3.1-11.el8.x86_64
systemd-239-41.el8_3.1.x86_64
selinux-policy-3.14.3-54.el8.noarch


## How reproducible:

# useradd testuser
# echo -e "session     required \t\t\t\t\t pam_tty_audit.so disable=* enable=testuser"  >> /etc/pam.d/password-auth
# echo -e "session     required \t\t\t\t\t pam_tty_audit.so disable=* enable=testuser"  >> /etc/pam.d/system-auth
# reboot


## Expected results:

No AVC logs


## Additional info:

Workaround, custom module:

    module audit4systemd 1.0;
    
    require {
    	type init_t;
	class capability audit_control;
    }
    
    #============= init_t ==============
    allow init_t self:capability audit_control;
