Bug Bounty Zip ed54e99482 Add Fedora 44 (GNOME) image support
New fedora distro: distrobuilder fedora-http recipe with full GNOME
desktop (GDM autologin), the PS5 IW620 internal WiFi modules built from
nxp-imx/mwifiex + ps5-linux-mwifiex, and an RPM packaging path for the
shared PS5 kernel (docker/kernel-builder-rpm).

Notable PS5-specific fix: the kernel patches write into the
request_firmware() buffer to skip the firmware signature header
(gfx_v10_0_early_init, amdgpu_sdma_init_microcode). Fedora ships
firmware xz-compressed, and the kernel maps xz-decompressed firmware
read-only (fw_decompress_xz_pages -> fw_map_paged_buf -> vmap
PAGE_KERNEL_RO), so the write oopses amdgpu before /dev/dri exists and
the display never comes up. Distros with zstd or uncompressed firmware
decompress into writable buffers, which is why only Fedora was
affected. The recipe therefore ships the cyan_skillfish GPU firmware
uncompressed, materializing linux-firmware's dedup symlinks first
(unxz refuses symlinks).

Also installs umoci/skopeo in the image builder (Fedora 41+ bases ship
as OCI archives) and wires fedora into build_image.sh (FORMAT=rpm) and
the image-builder entrypoint.

Tested on PS5 hardware: GNOME displays over HDMI, internal WiFi scans
and connects.
