Dexpreopt: use "speed-profile" if a system server jar has a profile.

Browse source 
The motivation is to reduce file size and in-process memory footprint
for "services" (which is currently the only system server jar that has a
profile). For other system server jars that have no profile keep using
"speed", as enabling "speed-profile" for them would completely disable
AOT-compiled code.

Compare .odex file size:
  - before: 44360 services.odex
  - after:  24968 services.odex
