python3-pylint: fix astroid 4.1.2 functional-test fixture mismatches

astroid 4.1.2 (the version this distro packages) changed how it
resolves the enclosing scope/parent name and end_lineno for decorated
functions, singledispatch registrations, positional-only-arg checks
and a few other node kinds. These functional tests were pinned against
an older astroid's output and fail with plain output-text mismatches
(not logic errors) once run against 4.1.2. Regenerated the expected
.txt fixtures against astroid==4.1.2, mirroring the existing
0001-Adjust-test-expectations-for-ptest.patch approach for this
recipe.

tests/functional/u/undefined/undefined_variable.314.txt is pylint's
own Python-3.14-specific override of undefined_variable.txt (see
FunctionalTestFile.expected_output, which prefers a
"<base>.<ver>.txt" file over the plain one when it matches the
running interpreter). The distro's target Python is 3.14.7, so this
file - not the plain .txt - is what actually gets read during ptest,
and it still carried the pre-4.1.2 astroid values for the same two
lines. Applied the identical fix there too.
