Ensure hermetic device rust_bindgen.

Browse Source 
rust_bindgen was not hermetic previously as it would pull in host
headers for device targets. This fixes that by using the same flags we
use when compiling with Clang. This also makes sure our rust_bindgen
headers are built as similar as possible to their respective
cc_libraries.

This also pulls in the bionic dependencies as well, which provide the
headers required for device targets.

Bug: 162007475
Test: device rust_bindgen deps file does not reference host headers.
