Targeting the rpiboot directory directly confuses ninja when inner files change (Missing restat warning, outputs should be files error). Use a stamp file (.stamp) so ninja correctly detects when the directory contents are stale. Also uppercase the FAT volume label BOOT to avoid mkfs.fat's lowercase label compatibility warning.
