python-pip: bump to 26.2.1

Refresh sha256 from the PyPI sdist and refresh 003 for the shifted line.

Retarget 002-pip-runner-pyc-fix.patch instead of dropping it: in 26.2.1
get_runnable_pip() moved from build_env.py (now a package) to
_internal/utils/misc.py. The function is otherwise unchanged and still
returns __pip-runner__.py, so the .pyc fallback is still required. We ship
pip byte-compiled only (the .py sources live in the -src package), so
without it build isolation cannot locate the runner and every PEP 517
install fails on target. This is a packaging workaround, not an upstream
bug, so upstream has no reason to carry it.

+Subject: [PATCH] build isolation: fall back to __pip-runner__.pyc
+
+get_runnable_pip() returns the path of __pip-runner__.py so pip can run
+itself in a subprocess to populate the PEP 517 build environment. We ship
+the pip package byte-compiled only (the .py sources live in the separate
+-src package), so the .py file is absent on target and build isolation
+fails. Fall back to the .pyc when the source is not present.
+
+Not an upstream bug: upstream always ships the .py, so it has no reason to
+handle this. In pip 26.2.x get_runnable_pip() moved from build_env.py to
+_internal/utils/misc.py (build_env.py became a package), which is why the
+old patch stopped applying; the function itself is unchanged and still
+hardcodes __pip-runner__.py, so this workaround is still required.
