Android builder is out of free space

See the build logs from servo/servo#11766 (comment) for proof.

This is cross1; I removed some old stuff to hopefully get us in a better place right now.

Took a look with ncdu.

A while ago, we changed the locations of various dependencies (Android SDK, NDK, etc.) on disk to better handle multiple versions and updating. servo-linux-cross1 was first deployed before these changes and still had the old folders floating around. I've renamed them to add -OLD suffixes, and if a build successfully completes, I'll delete them.

@Ms2ger do you remember what you deleted, so it can be automated?

I checked via Salt and servo-linux-cross2 is also at 99%..remediating now.

http://build.servo.org/builders/android/builds/1486 succeeded, so I went and deleted the folders. servo-linux-cross1 has 49% usage of the primary disk and servo-linux-cross2 has 58% of the primary disk, so we should be fine.
