mkinitramfs:Reduce terminfo and kernel modules

This reduces the terminfo directory, which is currently over 40 MB
uncompressed, to just copy in the `l` directory, as the bootup tty is a
`linux` terminal, so we only need terminfo for that.

This also adds additional removals from the kernel device drivers
directory for modules that are not required during the boot process.
