Leave the tar extraction fallback where it was

Refusing the install on a Python without the extraction filters is a
change to how every archive on every platform is unpacked, and it has
nothing to do with shipping a Vulkan whisper-server. On those Pythons
the download stops working altogether, which is a worse answer than the
one that was there.

Worth doing on its own terms, in its own change, where the versions it
turns away can be argued about without a backend release riding on it.
