V-71849 Command Enhancement

[t0sche]

This regex does not seem to be valid. When executed, it does not return the expected values.

redhat-enterprise-linux-7-stig-baseline/controls/V-71849.rb

Lines 19 to 21 in 4d1347c

	# for i in `rpm -Va | egrep -i '^\\.[M|U|G|.]{8}' | cut -d \" \" -f4,5`;do
	for j in `rpm -qf $i`;do rpm -ql $j --dump | cut -d \" \" -f1,5,6,7 | grep
	$i;done;done

I have tested this instead and it appears to work as intended based on the control text:

for i in `rpm -Va | egrep '^.{1}M|^.{5}U|^.{6}G' | cut -d " " -f4,5`;do for j in `rpm -qf $i`;do rpm -ql $j --dump | cut -d " " -f1,5,6,7 | grep $i;done;done

Update the corresponding check based on the above command:

	it { should all(be_in rpm_verify_perms_except) }
