Use custom function to hack props without increasing prop change counter

- some apps were detecting tampered props from the increased prop_info serial counter using resetprop
- patching doesn't rely on magiskboot hexpatch so should work on KernelSU and APatch as well
- hopefully temporary until all root solutions adopt a patched system_properties repo to fix counters via resetprop
