Peripheralman: Remove IIO from ioinit for android

Since peripheral manager does not build in the IIO source, ifdef's were
added around the initio functionality for IIO.

IMO this is an ugly fix, but I don't see a better way since the
PERIPHERALMAN architecture is qualified throughout the CMake and source
with ifdef's.
