[PATCH] license.py: Drop visit_Str from SeenVisitor in selftest

[sunilkumar.dora]

From: Sunil Dora <sunilkumar.dora@windriver.com>

ast.Str was deprecated in Python 3.8 and removed in Python 3.14.
In [1], visit_Str was already removed from the LicenseVisitor
subclasses (FlattenVisitor, ListVisitor) in oe/license.py since
bitbake now requires Python 3.8+.

However, the test-only SeenVisitor class in the selftest was
missed at that time and still uses visit_Str/node.s. On Python
3.14, ast.Str is fully removed so visit_Str is never called,
causing test_single_licenses to return [] instead of the
expected license list.

Replace visit_Str/node.s with visit_Constant/node.value in
SeenVisitor.

Fixes [YOCTO #16220]
