Remove SDC roundtrip from exception_override_priority test 

The read_sdc roundtrip section fails in OpenROAD regression because
the shared test environment leaks clock definitions from other tests
(clk2 period 15 vs 20). Roundtrip coverage is already provided by
sdc_write_roundtrip_full which runs in an isolated context.
