    gdb: Use correct feature in tdesc-regs for ARC
    
    tdesc-regs.exp test fails for ARC because the test is not
    using the correct XML files as target description.  With
    this change, the correct directory and files are used.
    
    v2 (after Andrew's remark [1]):
    - Update the feature file names again.  Test results now:
    
      Test run by shahab on Tue Jan 26 11:31:16 2021
      Target is arc-default-elf32
      Host   is x86_64-unknown-linux-gnu
