Jetifier outputs are not deterministic

[Bencodes]

We are finding that the version of Jetifier being used by rules_jvm_external does not produce deterministic outputs. When comparing the execution binary files for two builds we see the following:

Both builds are fetching the same artifact with the same hash:

listed_outputs: "bazel-out/android-armeabi-v7a-fastbuild/bin/external/maven/v1/.../com/makeramen/roundedimageview/2.3.0/roundedimageview-2.3.0.aar"
remotable: true
cacheable: true
progress_message: "Executing genrule @maven//:com_makeramen_roundedimageview_2_3_0_extension"

}

First build:

Second build:

It looks like Jetifier 1.0.0-beta10 already has support for --timestampsPolicy but a standalone release hasn't been pushed to https://developer.android.com/studio/command-line/jetifier
