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?).
