Subject: [PATCH] fix: pass ffmpeg_path to birdseye encode preset format string

When hwaccel_args is a list (not a preset string), the fallback in
parse_preset_hardware_acceleration_encode() calls
arg_map["default"].format(input, output) with only 2 positional args.
But PRESETS_HW_ACCEL_ENCODE_BIRDSEYE["default"] contains {0}, {1}, {2}
expecting ffmpeg_path as the first arg.

This causes IndexError: Replacement index 2 out of range for size 2
which crashes create_config.py on every go2rtc start, taking down
all camera streams.

Pass ffmpeg_path as the first argument to match the preset template.
