Extension for the binder_linux module

[muvaf]

The module binder_linux is required for running Android as Linux containers. Waydroid and Redroid are example projects and both require loading this module via:

# If not exists, install it first with: apt install linux-modules-extra-`uname -r`
modprobe binder_linux devices="binder,hwbinder,vndbinder"

As Talos is pre-built with a set of modules, it's not possible to install extra modules and binder_linux doesn't appear in the included module list.

modprobe: FATAL: Module binder_linux not found in directory /lib/modules/6.6.28-talos

From the look of it, it'd be pretty straight-forward to add a folder under misc similar to binfmt-misc module extension. I can take a stab at it but may need some hand holding as I never worked directly with Linux kernel before.
