apparmor: Drop 'Last modified' comment from profiles

At the beginning of each profile we have a comment that says when
the profile was last updated. In theory, it makes sense because
one can see immediately if they are using an outdated profile.
However, we don't do a good job in keeping the comments in sync
with reality and also sysadmins should rather use their package
manager to find out libvirt version which installed the profiles.
