travis: Add non-print,debug builds for all targets

By default we have more or less done Travis builds with

  CFG_TEE_CORE_LOG_LEVEL=4 DEBUG=1
  CFG_TEE_CORE_LOG_LEVEL=0

Implicitly the CFG_TEE_TA_LOG_LEVEL has been set to 3 and due to this we
have in some cases missed things like the issue described in:
https://github.com/OP-TEE/optee_os/issues/848

We should also let Travis build "no debug, no debug-print" builds to
capture such errors and therefore we've added/changed all
  CFG_TEE_CORE_LOG_LEVEL=0

to instead say
  CFG_TEE_CORE_LOG_LEVEL=0 CFG_TEE_TA_LOG_LEVEL=0 DEBUG=0
