mdio-tools: update to version 1.0.1

Version 1.0.1 brought the following changes:
[v1.0.1] - 2021-11-26

Primarily fixes a few issues in the kernel module that were found
during a quick review from Russell King:

https://lore.kernel.org/netdev/YYPU1gOvUPa00JWg@shell.armlinux.org.uk/

- mdio: The mvls subcommand now supports flushing the ATU

- mdio-netlink: Plug some glaring holes around integer overflows of
  the PC.
- mdio-netlink: Release reference to MDIO bus after a transaction
  completes.

So, update to the latest version and switch the kernel module back
to fetching tarballs like the userspace tool does.
