optee-ftpm: Add TI version override for ftpm

We are missing the optee-ftpm package verson override along with our
other optee-* overrides.  This resulted in a build error when meta-arm
moved to 4.7.0 while we are still sitting on 4.6.0.  The 4.7.0
optee-ftpm is using some new header info that the 4.6.0
optee-os-tadevkit is not providing.
