    gdb/testsuite: fix gdb.trace/signal.exp on x86
    
    Patch
    
      202be274a41a ("opcodes/i386: remove trailing whitespace from insns with zero operands")
    
    causes this regression:
    
      FAIL: gdb.trace/signal.exp: find syscall insn in kill
    
    It's because the test still expects to match a whitespace after the
    instruction, which the patch mentioned above removed.  Remove the
    whitespaces for the regexp.
