birdcage: Split out 3rdparty deps to be opened

These 3rdparty BUILD files will be "open sourced" to support their (already opened) dependees. As a side benefit, the massive 3rdparty/BUILD file shrinks a bit.

- Explode initial set of (open source dependee) 3rdparty deps out from 3rdparty/BUILD.* and into subdirectories

This was produced by splitting out the dependencies of finagle, util, scrooge and twitter-server (computed via depmap: see attached ticket) manually into subdirectories, and then using a script like the following for each moved target:

    find . -name 'BUILD*' | xargs egrep --color=auto -i -s "$1" | xargs sed -i '' "s|$1|$2|g"
