libcameraservice: Support FFCs with reversed rotation logic

Double mirroring, how does it work? :(

This also does a revert of change I795b216228da46ee98efc8540ada1780d00b18d8,
("libcameraservice: Add exceptions to handle the FFC on the LGE star")
since it serves the same purpose in a better (and generic) way.
