[TestFix] Changing code used to create arbiter volumes

As distributed-arbiter and arbiter weren't present before patch [1],
arbiter and distributed-arbiter volumes were created by the hack show
below where a distributed-replicated or replicated volume's configuration
was modified to create an arbiter volume.
```
@runs_on([['replicated', 'distributed-replicated'],
          ['glusterfs', 'nfs']])
class TestSelfHeal(GlusterBaseClass):
   .................

   @classmethod
   def setUpClass(cls):
    ...............

     # Overriding the volume type to specifically test the volume
     # type Change from distributed-replicated to arbiter
     if cls.volume_type == "distributed-replicated":
         cls.volume['voltype'] = { 'type': 'distributed-replicated',
                                   'dist_count': 2,
                                   'replica_count': 3,
                                   'arbiter_count': 1,
                                   'transport': 'tcp'}
```
Now this code is to be updated where we need to remove code which
was used to override volume configuration and
just add arbiter or distributed-arbiter in `@runs_on([],[])`
as shown below:
```
@runs_on([['replicated', 'distributed-arbiter'],
          ['glusterfs', 'nfs']])
class TestSelfHeal(GlusterBaseClass):
```
