[split] Fix straggling dependencies in birdcage poms

Problem

Some dependencies in birdcage maven were still pointing to old TWOTEN
versions even after the in-repo poms are now snapshot versions.  This
will very quickly lead to horribly broken artifacts for everybody in the
above groups.
Additionally, the parent poms were being republished in the snapshot CI
build.

Solution

Set dependencies to point to their correct SNAPSHOT targets.
Also fix parents to be SNAPSHOT targets so that they will not land in
the reactor for their children (this fixes `mvn -am deploy`)

[split] scrooge: Fix travis build.

This change is bringing back Jeff's change https://github.com/twitter/scrooge/pull/110

RB_ID=455529
[split] Address or suppress warnings.

Add `-deprecation` to `scalacOptions`, and `-Xlint:unchecked` to `javacOptions`, so we see details of warnings.

For *Classpaths.publishConfig* is deprecated*, set `overwrite = true`.

For *unchecked cast*, add `@SuppressWarnings("unchecked")`.

For *Possible heap pollution from parameterized vararg type T*, add `@SafeVarargs`.

[split] scrooge-serializer: Remove dependency on scrooge-runtime

Problem

It would be nice to publish scrooge-serializer against 2.11.  For
example, algebird depends on it.

Solution

Because scrooge-serializer only depends on features in scrooge-core,
we can publish properly for scala 2.11 today by changing the
dependency to be on scrooge-core instead of scrooge-serializer.

Result

We can now publish scrooge-serializer against 2.11.

[split] birdcage: Remove excess maven_layout usage.

maven_layout sets up source roots for scala/java/tests/etc, rooted at the location it is used in a BUILD file. Thus, it should only be used in places where `src/(main|test)/(java|scala)` are expected. New validation in the latest version of pants (occasionally) disallows this.

- Remove excess maven_layout usage.
