ipa: raspberrypi: Fix crash under LTO

Browse source 
When compiled with LTO (the default on Ubuntu), the global static
objects camHelpers and algorithms cause a crash in raspberrypi_ipa_proxy
at runtime as they're not allocated by the time the registration
routines execute.

This is a fairly crude fix which just converts the global static objects
into local static objects inside an equivalently named function.
