            [enhancement] Add test suite fixes for '--with tests' builds

Add Patch4 'test-fixes.patch' with fixes for the test suite:

1. 'test_errors.py': Python 3.15 changed the TypeError message for
   insufficient %-format arguments, appending '(got N)' to the text.
   Use 'startswith()' instead of exact equality to accept both the
   old and new message format.

2. 'test_connection.py': Skip 'test_shutdown' — it asserts that the
   'Aborted_clients' counter increments by exactly 1 after a forced
   shutdown, which is timing-sensitive and fails intermittently in
   build environments.

3. 'generate.sh': OpenSSL 4.0 requires the Authority Key Identifier
   extension in signed certificates.  Add a '[usr_cert]' section
   with AKI, SKI, and proper key usage to the generated 'ca.conf'
   so that server and client test certs pass verification.

4. 'test_qa_ciphers.py', 'test_bugs.py': Python 3.15 removed the
   'ssl.PROTOCOL_TLSv1_2' constant (PEP 644).  Tests that force a
   TLSv1.2 connection via that constant fail with KeyError.  Skip
   9 tests when the constant is unavailable — the proper connector
   fix (using 'ssl.SSLContext' version pinning) belongs upstream.

Spec changes for test support:

- Add 'openssl' BuildRequires (conditional on '--with tests') for
  regenerating expired SSL test certificates via upstream's
  'generate.sh' — bundled certs ship with 365-day validity and are
  already expired as of 2026-07-23.
- Regenerate SSL certs in '%prep' before tests run.
- Pass '--unix-socket=/tmp' to 'unittests.py' in '%check' — the mock
  buildroot path exceeds MySQL's 110-character unix socket limit.
