[SYCL][NFC] Fix kernel_lambda_with_kernel_handler_arg.cpp test (#3467)

This patch avoids running this test on the host device as spec constants
for host device are not implemented yet. Instead, it runs with OpenCL CPU
because low-level runtime and devices are not important here - the impl
is backend-agnostic.
