ACardEmulator: Added F-Droid build flavor with FOSS only

- avoid precompiled JARs for JCardSim
- use gradle's shadow plugin to relocate JCardSim's use of Bouncycastle
- removes JCardSim's Hello world applet
- use vJCRE to avoid importing Oracle's api_classic.jar

(We may use vJCRE as full replacement for JCardSim in the future, but
JCardSim is currently the choice with more features and support)
