[Test] Drop 'sycldevice' from IR modules' triple information

Recent changes in the DPC++ compiler
(intel/llvm#3929) allow to disregard the
`sycldevice` component from the target triple in command lines. From
there on, IR files for the Translator tests should be produced using
the simplified target triple. Clean up the existing tests to match
this change.
