Feature request: classify whatever.BUILD files as bazel files

[TheButlah]

Currently identify has support for BUILD and BUILD.bazel files. it would be good to add support for *.BUILD files as well.

In case its helpful, here is the relevant regex that should describe a bazel file, when matching against a filepath:

^(.*/)?(BUILD\.bazel|BUILD)$|\.BUILD$

[asottile]

can you provide a reference for this? as far as I can tell in the official bazel docs they only use BUILD or BUILD.bazel

Here you go! https://docs.bazel.build/versions/1.2.0/external.html#depending-on-non-bazel-projects

Common to have a third_party folder, with dep1.BUILD, dep2.BUILD, to bazelify non bazel projects
