readline: enable HOME, END, INSERT, and DELETE key bindings in inputrc

Enable readline inputrc bindings for HOME, END, INSERT, and DELETE keys
to support common key sequences on terminal interfaces. These key
sequences are commonly emitted by terminal emulators and physical
keyboards.

This enables expected shell behavior on embedded systems, especially
when interacting over serial consoles or minimal terminal setups.
