Remove some unused CIPD packages before android compile. (#29530)

This should save about 2.5GB of space.
Ideally we should not download these in the first place,
however I would have to figure out how to set that up.

For now tested locally that compile seems to pass because we
use the NDK, however CI will fully validate this.
