Allow run_init_t to read all named init scripts

When OpenRC wants to execute a labeled init script, it fails if this is
a symlink:

~$ sudo /etc/init.d/ceph-mon.0 start
openrc-run should not be run directly

The denial shows that a read on the symlink is denied:

type=AVC msg=audit(1436621093.701:1165): avc:  denied  { read } for
pid=30786 comm="openrc" name="ceph-mon.0" dev="vda3" ino=1966780
scontext=staff_u:staff_r:run_init_t:s0
tcontext=system_u:object_r:ceph_initrc_exec_t:s0 tclass=lnk_file
permissive=0

After granting this, the behavior is as expected:

~$ sudo /etc/init.d/ceph-mon.0 start
* Starting Ceph mon.0 ...               [ ok ]
