[SYCL][E2E] Mark a test as unsupported on accelerator (#10037)

This test used to be only run on the CPU and GPU but when we moved to
the `%{run}` notation, it wasn't marked as unsupported on accelerator.
It seems unsupported on accelerator. The `clCreateProgramWithIL()` call
is returning and error -59 when the accelerator device is the one behind
the context. I went back and checked and it has never worked on
accelerator. I'll make a note in the online compiler tickets and if this
is a real error, a ticket will be opened. But the test should be
restored so to not be run on accelerator.
