Audit access to libart

Grant access to all processes and audit access. The end goal is to
whitelist all access to the interpreter. Several processes including
dex2oat, apps, and zygote were observed using libart, so omit them
from auditing and explicitly grant them access.

Test: Angler builds and boots
