[SYCL][E2E] Enable Regression/barrier_with_work.cpp on Linux (#21332)
https://github.com/intel/llvm/pull/21251 fixed a bug that could have
been the reason for failures. That PR also enabled the test Windows
because it no longer XFAIL-ed. I wasn't able to reproduce failures
manually on either PVC or BMG with a 100 runs each.
Fixes: #20600
