Russell Coker eba35802cc yet more tiny stuff 
I think this should be self-explanatory.  I've added an audit trace for the
sys_ptrace access that was previously rejected.

Here is the audit log for sys_ptrace:

Allow transition to dpkg_t with nnp, Dominick seems to imply this shouldn't
be necessary.

Lots of little stuff for system_cronjob_t.

Russell Coker 54136fa311 more tiny stuff 
I think the old timesync labelling wasn't working anyway due to -- for a
directory name.

A couple of patches for devicekit calling dmidecode (this is part of replacing
some kmem access that was discussed on this list and rejected as a misfeature
in Debian DMI related code ages ago).

The rest should be obvious.

This change is setting the type for the file /etc/hostname to
net_conf_t and granting hostnamectl permission to edit this file.
Note that hostnamectl is initially creating a new file .#hostname*
which is why the create permissions are requied.

selinuxutil: restorecond is buggy when it dereferencies symlinks 
restorecond uses libselinux's selinux_restorecon() to relabel files,
which dereferences symlinks in a useless call to statfs(). This produces
AVC denials which are noisy.
