[OE-core][PATCH] python: prevent build failure when pycache files missing

[Athanasios Oikonomou <athoik@gmail.com>]

Building a patched version of python3 with byte-code files saved to their legacy locations and names causes the following errors:

| rm: cannot remove '/.../build/tmp/work/x86_64-linux/python3-native/3.9.9-r0/recipe-sysroot-native/usr/lib/python3.9/test/__pycache__/test_range.cpython*': No such file or directory
| rm: cannot remove '/.../build/tmp/work/x86_64-linux/meson-native/0.57.1-r1/recipe-sysroot-native/usr/lib/python*/site-packages/mesonbuild/dependencies/__pycache__/mpi.cpython*': No such file or directory

Force remove pycache files, preventing build failure in case they are absent.

Python3 patched with legacy byte-code locations in order to create a sourceless .pyc deployment for small flash boxes. Unappropriate for upstream.
