Cedric Roux 18e59d3c2e lte: switch to RRC release 16.13.0 
A COTS UE is sending UE capabilities with accessStratumRelease "rel16"
which is not decoded by our RRC. Switching to RRC 16.13.0 lets our RRC
accept these capabilities (and as a positive side effect lets this
particular UE work nicely in NSA fr1).
