redbear-mini: drop GPU/generic firmware — text-only image was ~3G

redbear-firmware (~1.9G), redbear-firmware-intel (~396M) and
redbear-firmware-amdgpu (~111M) staged GPU/DMC/generic linux-firmware blobs into
a TEXT-ONLY console image (no GPU accel in text mode) — ~2.4G of dead weight that
blew the image far past its size budget and overflowed the installer
('No space left on device' at the disk-image step). Keep only the small NIC/BT
firmware (redbear-firmware-iwlwifi + -bluetooth, ~444K each) + firmware-loader.
Image drops to ~600MB (< 700MB target). GPU firmware belongs to redbear-full.
