[SYCL][E2E] Add XFAIL for fpga to OCL_interop_test.cpp (#16916)

Add `XFAIL: accelerator` to `OCL_interop_test.cpp` because of
[this](https://github.com/intel/llvm/actions/runs/13187415776/job/36814982904)
and remove a rogue print statement meant for debugging purposes during
development which is most likely unrelated to the failure.
An issue for the failure has also been created
#16914
