this is just a hook so its safe
without this change:
we build a python3 for buildHost twice instead of only once while the result
of the build is the same

This was previously disabled because pkgs.udev (=pkgs.systemd) was not building on musl, but that is no longer the case.
This fixes the build of pkgsMusl.usbutils, which requires udev support in libusb1.
Since the Nix command used is an implementation detail of the script,
it's the script that will have to be updated if the command changes,
it's the script that should be opting into this, rather than making
the user do it globally.
Since c0972c16dc ("update-python-libraries: add missing dependency nix"),
Nix will be provided as a dependency, so we know we'll always be using
a modern version and no longer need the fallback.
The latest bcrypt version segfaults during test_kdf, which prevents the
package from building. The package is in the critical chain for many
NixOS tests, which currently won't complete on i686-linux.
