[Buildroot] [git commit branch/2022.02.x] support/testing/tests/package/test_python_botocore: use ext2 instead of cpio

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=06a62ca64ed203c3630f02733636e3c49d28342c
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2022.02.x

The CPIO filesystem generated by the test_python_botocore test is too
large, and doesn't fit as an initramfs in the 256MB of RAM available
in the versatilepb machine. This causes a "Initramfs unpacking failed:
write error" when booting, and many files being missing from the root
filesystem, ultimately causing the test to fail.

It would make sense to switch all test cases to use ext2 + a
hard-drive, but for now, let's fix the few test cases that are causing
problems.
