[action] [PR:9208] [tests/crm] Fix python3 syntax error in test_acl_entry

[mssonicbld]

Description of PR

Summary:
Testcase crm/test_crm.py::test_acl_entry hit below error in Python3 env:

 def test_acl_entry(duthosts, enum_rand_one_per_hwsku_frontend_hostname, enum_frontend_asic_index, collector, tbinfo):
 duthost = duthosts[enum_rand_one_per_hwsku_frontend_hostname]
 asichost = duthost.asic_instance(enum_frontend_asic_index)
 asic_collector = collector[asichost.asic_index]

 if duthost.facts["asic_type"] == "marvell":
 # Remove DATA ACL Table and add it again with ports in same port group
 mg_facts = duthost.get_extended_minigraph_facts(tbinfo)
 tmp_ports = mg_facts["minigraph_ports"].keys()
> tmp_ports.sort(key=lambda x: int(x[8:]))
E AttributeError: 'dict_keys' object has no attribute 'sort'

The root cause is, in python2 dict.keys() returns a list object, but in python3 it returns a dict_keys object which is not sortable.

Use sorted() function instead of dict.keys().sort(). sorted() function can put the keys of a dict in a list in sorted order, and it has same action in Python2 and Python3.
