ipa: raspberrypi: Fix crash under LTO
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.
