BUG: SV-238235 is looking for pam_tally instead of pam_faillock

[pbarrette]

The STIG is looking for the pam_faillock.so module, but the control is searching for the pam_tally module

A correction would be something like this:

    describe command('grep faillock /etc/pam.d/common-auth') do
      its('exit_status') { should eq 0 }
      its('stdout.strip') { should match(/^\s*auth\s+\[default=die\]\s+pam_faillock.so\s+authfail$/) }
      its('stdout.strip') { should match(/^\s*auth\s+sufficient\s+pam_faillock.so\s+authsucc$/) }
    end
