RISC-V: Update test expectancies with recent scheduler change

RISC-V: Update test expectancies with recent scheduler change

Given the recent change with adding the scheduler pipeline descriptions,
many scan-dump failures emerged. Relax the expected assembler output
conditions on the affected tests to reduce noise.
