build_test.py: set env vars for cross compile

Browse source 
Now that minijail-sys is added a simple run of ./build_test fails with
messages like:

error: failed to run custom build command for `minijail-sys v0.0.11
(/mnt/host/source/src/aosp/external/minijail)`

thread 'main' panicked at 'called `Result::unwrap()` on an `Err`
value: CrossCompilation', src/libcore/result.rs:1165:5

This change adds various environment variables to address the problem.

BUG=None
TEST=./build_test.py --arm-sysroot /build/cheza/ --aarch64-sysroot /build/kevin64/
