[OE-core] python3-pip: drop unused Windows distlib launcher templates

[krkapate@cisco.com]

From: Krupal Ka Patel <krkapate@cisco.com>

pip vendors distlib which ships Windows launcher template binaries
(*.exe) under pip/_vendor/distlib. These files are only used on
Windows systems but are installed and packaged for target, native,
and nativesdk builds.

Remove the distlib *.exe templates when not building for a mingw
(mingw32/mingw64) host to avoid shipping unused Windows binaries and
reduce package noise.
