Use Proguard -systemjars instead of -libraryjars

Browse Source 
Proguard -systemjars will correctly use the system libraries version
of a duplicate class rather than the program's version.

If USE_R8=true then use -libraryjars as R8's proguard emulation layer
does not support -systemjars and it is unnecessary because R8 does not
fail like proguard does when it comes across duplicate classes.
