Commit c268a82 "key-duplicates: Don't crash on redundant closing
brackets or braces" fixed a problem but introduced another one: it
crashes on systems with (I guess) an old version of PyYAML. This is
probably linked to the "Allow colon in a plain scalar in a flow context"
issue on PyYAML [1].
For example, this problem happens on CentOS 8:
FAIL: test_disabled (tests.rules.test_key_duplicates.KeyDuplicatesTestCase)
----------------------------------------------------------------------
Traceback (most recent call last):
File "…/tests/rules/test_key_duplicates.py", line 90, in test_disabled
'{a:1, b:2}}\n', conf, problem=(2, 11, 'syntax'))
File "…/tests/common.py", line 54, in check
self.assertEqual(real_problems, expected_problems)
AssertionError: Lists differ: …
- [2:3: syntax error: found unexpected ':' (syntax)]
+ [2:11: <no description>]
I propose to simply fix the *space following a colon* problem, since
it's not related to what the original author @tamere-allo-peter tried to
fix.

The `# -*- coding: utf-8 -*-` headers were useful for Python 2, and
aren't needed for Python 3 where UTF-8 is the default.
yamllint support of Python 2 was dropped in early 2021, see commit
a3fc64d "End support for Python 2".
Let's drop these headers.
