emulator: Enable dex-preoptimization in emulator-specific builds
This patch re-enables dex preoptimization in emulator-specific
builds. This considerably speeds up the first-boot of SDK AVDs
since the dex optimization pass is performed during the build
instead.
This was enabled in a previous patch, then reverted due to a
bug in the build system that has been fixed since.
This patch doesn't affect any device build.
