Cycles: re-enable zebin format for Intel GPUs on Linux

zebin format is critical for the compatibility of AoT graphics binaries
across driver versions. It was previously disabled on Linux due to
runtime issues that are now fixed in
https://github.com/intel/compute-runtime/releases/tag/22.31.23852.
The minimum supported driver version isn't bumped to this one yet as
current codebase with current IGC compiler does actually run fine on
earlier drivers and is not running into these issues anymore.
