optee-os: add SDK environment script to build trusted applications 

Building Optee trusted applications (TA) depends on optee_client and the TA
devkit provided by optee_os. Our toolchain provides those dependencies, but
the SDK script which configures the environment for standalone building,
is not configuring some variables needed to build trusted applications.

This commit extends the SDK environment script to allow building TAs.
