This removes a few globs from the mkinitramfs module copy part. This is an issue
in linux-postmarketos since it will copy gpu drivers for all possible hardware to the
initramfs.

This should be done in the deviceinfo variables for the modules instead and is
already done for the current devices that use module loading. This changes the
initramfs (uncompressed) from 16 MB to 11 MB just because the qemu graphics
drivers aren't included.
