Add deps attributes to the Skylark maven_{a,j}ar rules.

The deps are passed through into the generated java_import and aar_import rules. This is necessary for AARs with resource dependencies since maven_aar ignores transitive dependencies. It's less significant for the Java rules, since typically JARs on Maven are compiled class files and as such only have runtime dependencies.

Example usage:

```
# WORKSPACE
load("@bazel_tools//tools/build_defs/repo:maven_rules.bzl", "maven_aar")
maven_aar(
    name = "android_image_cropper",
    artifact = "com.theartofdev.edmodo:android-image-cropper:2.3.1",
    deps = [
        "@androidsdk//com.android.support:appcompat-v7-24.1.1",
    ],
)
```

Fixes https://github.com/bazelbuild/bazel/issues/2863.
Fixes https://github.com/bazelbuild/bazel/issues/3980.

Also, cleans up some broken stuff in the tests (sadly, they don't run on jenkins, so nothing caught that they were broken). test_maven_jar_with_classifier_skylark still does not work, so I disabled.

RELNOTES: Add deps attribute to Skylark maven_aar and maven_jar workspace rules.
