arduino-uno-q: move flash binaries to armbian/qcombin

Move EDL flash binaries (ABL, XBL, TrustZone, GPT tables, etc.) from
packages/blobs/arduino/flash/ to the external armbian/qcombin repository
under the Agatti folder, following the same pattern as rkbin for
Rockchip and mtkbin for MediaTek.

Add qcombin.sh extension to fetch binaries during build. Update
image-output-arduino.sh to source flash files from qcombin cache and
derive U-Boot package path from BRANCH/BOARD variables.
