[OpenWrt-Devel] [PATCH v2 1/3] scripts: target-metadata don't add PROFILES twice

[Paul Spooren]

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 twices when
running `make info`.

This patch uses Perls `uniq` function to add the profiles only once to
`.profiles.mk`.

v2:
  * Instead of importing the entire MoreUtils library only copy the
    `uniq` function.
