[SYCL] disabling two test clauses while opening a JIRA (#16699)

to address post-commit failure here:
#16693


This fpga_pipe.cpp test has been passing because it was using the wrong
binary operation to fold together test results. I fixed this in this and
some other tests recently. My PR passed the CI because, apparently, we
don't have exercise the FPGA accelerator (or emulator) there.

fpga_pipe.cpp tests 12 different combinations, the last two (
`test_array_th_nb_pipe` and `test_array_th_bl_pipe` ) are failing.
Opening a JIRA.
