gfx1100 is missing a flagsfile.

[AWoloszyn]

Even when specifying a local flagsfile, it tries to download one (and fails).

 python -m shortfin_apps.sd.server --fibers_per_device=4 --workers_per_device=1 --target=gfx1100 --model_config=./python/shortfin_apps/sd/examples/sdxl_config_i8.json --device=amdgpu --flagfile ./python/shortfin_apps/sd/examples/sdxl_flags_gfx1100.txt --build_preference=compile --device_ids 0 1
 ....
 ....
 OSError: Failed to fetch URL 'https://sharkpublic.blob.core.windows.net/sharkpublic/sdxl/11132024/configs/sdxl_flagfile_gfx1100.txt': HTTP Error 404: The specified blob does not exist.

I added a flagfile to azure which should let you past this -- the builder always fetches the required files even if an alternative is provided via the CLI. This is inefficient and wrong and is tracked in #525
