Rotating logger preserves file mode and ACL

This checks that the rotating logger preserves file mode and file
access control list which a user set on the log file before executing
dnf.

It enables a test for the file mode and adds a new test for ACL.

Because log rotation only works outside of installroot, it adds
no_installroot tag to the tests.

Because behave fails to execute multiple no_installroot scenarios from
one feature file, it moves them into separate files.
