Exempt-From-Owner-Approval: cherry pick
(cherry picked from commit 63cffd0246)
This is the only user of nosystem, and it doesn't seem to serve
any purpose since most of the system flags are then manually
included back again. Switch to optimization + obfuscation and
let the build system provide the correct flags file.
Test: classes.dex is identical, classes-proguard.jar differs only
in removed StackMapTable sections (from -dontpreverify?).
