Ensure dexopt on Marshmallow

This is a follow-up on 01c3244. The
same issues occur also on Marshmallow. It seems that they usually don't
show up because adjustCpuAbisForSharedUserLPw already compiles the
providers. Especially LG's providers don't seem to be processed there
and therefore cause bootloops.

Fixes rovo89/Xposed#100.

Fix creation of ResourcesKey objects on Marshmallow

The token parameter is gone, so we're back to the signature of SDK17 & 18.
CM13 will need two additional parameters though.
