fix(kernel-network-modules): also install modules from mdio subdirectory

A recent change in Linux kernel v5.10 split the MDIO drivers from the PHY
subdirectory into a new MDIO subdirectory [0]. This caused MDIO drivers
to not be included in the initramfs.

Also include the modules of this new subdirectory to prevent this issue.
