    scripts: target-metadata don't add PROFILES twice
    
    Since 4ee3cf2b5a profiles with alternative vendor names may appear
    multiple times in `tmp/.targetinfo` or `.targetinfo` (for
    ImageBuilders).
    
    The `target-metadata.pl` script adds these profiles then twice to
    `PROFILE_NAMES` and the ImageBuilder show the profile twice when running
    `make info`.
    
    This patch removes duplicate profile IDs and only adds them once to
    `.profiles.mk`.
